I’ve been curious if anyone has applied this logic and now I have my answer! Thank you for sharing this awesome exhaust setup! Sounds great! Keep doing things outside the norm!
@@muslwgn1871 Or even after. I have seen a few V8 show cars (and non V8 but meh on those. lol) that looked all sorts of mean, but then had shitty exhaust notes and it just ruined the whole car for me.
@@Superthecod Well yeah, considering GM ran with a 5.7L (350 Smallblock) for something like 40 years before going to the LS series. I consider the 6.0L LS2 in my CTS to be of a medium size.

I used to have a 99 Silverado single cab step side Z71 and that was my absolute favorite truck. Lifted, fox suspension, flowmaster pipe, HELLA Desert lights, pre-runner skid plate, man I miss that truck
I love a big single exhaust. Sounds good on everything in its own way. My sister did a 4 inch straight pipe on a 4.0 grand Cherokee in high school. It idled like a Cummins and revved like an Indy car. Weirdest shit I've ever seen.
Had an old neighbor with a similar setup, just had an old diesel stack cut way down from under the rear door and somehow straight out and it rumbled from a mile away
I had a friend customize a cone shaped intake for the 4.0L Cherokee back when you couldn't buy one. He made it from some PVC pipe and an open air cone filter for a Honda Civic. It had a pretty nice sound at high RPM. That with a magna flow exhaust and 5 speed manual, back in the late 90s, it was a sleeper.
Sounds great, everyone thought I was dumb for doing 3" single exhaust with a MagnaFlow 3" straight through muffler and a 3" dump in front of the axle. Mines very subtle until you stab it, then it really talks to you. My truck is stock with a home made cold air, stock converters and the 3" single custom made (by me) cat back exhaust. It's a 2000 extended cab 4x2 with a 5.3 and 4L60E. It's got 286,000 miles on it and I drive it daily. It's a super fun truck, sounds great and runs very very well. Glad yours sounds like mine and you like it. Great job, keep it up.
I am running the same setup as u except the muffler brand but I get a lot of compliments on the sound its suttle until you stab it next to the guy texting while driving and he drops his phone...lol that works for me
I had a vehicle with a 5.3L swap and it had single 3' with a Magnaflow and it sounded absolutely amazing. Unfortunately, the person who did the exhaust, did a horrible job of routing it. It was an off-road vehicle and I needed it redone for ground clearance. Went with a true dual setup and it sounded like garbage.
Wrap the y pipe under the transmission. Itll radiat heat into the transmission. Noticed it on my 2017. Wraped the left bank under the pan. Solved the heat soak.

Sounds great! Nice work. Exhaust pulse is one of the most interesting things about building cars. Look into 180 headers. There’s a guy that builds them for his BMW that has a 5.3 swap in it and it sounds wicked
The whole X-pipe scavenging effect reminds me of 2 stroke dirt bikes with the fatty pipes using the scavenging effect to make the engine run one way or another. Either way that thing sounds dope!
A lil tip that helped me. They sell mock flex tubing in required OD tubing your using to get the angles and path desired. They fit tight around the steel mock set up and allow to manipulate how ever you need to find the right path to connect tubing. But , beautiful work sir!
I had a 383 in an s10 once. 2.5" from the headers Y'd into a single 3." I used a huge RV 3.5" ID straight through muffler, then Y'd back into dual 2.5" tail pipes. Mild cam, so not too loud or rowdy, but that exhaust was super low sounding. Made it sound like a huge motor was in there, lol.
So glad I found you here,was so disappointed when channels changed and lost my Sunday morning fix of the lineup of shows that really got me going.You are so talented, educated and a real inspiration to me to someday crawl around under my truck and attempt an exhaust as clean as yours.Sounds so sweet.Thank-you Lawrence.Cheers
I did basically the same thing on my 5.8 windsor. 2 1/4 to a single 3” x 12” long resonator into a holley single inlet flowmaster with dual 2 1/2” out the back. Sounds similar to your truck. I love it.
The black widow muffler on my 5.3 LS has a dual 3" inlet and single "3 outlet. It has 1 7/8 headers with vbands to an x pipe similar to the one you show. (May even be the same). So after the x pipe it has a 30" dual straight section to the black widow dual to single. With another vband flange on the outlet. Has a single 3" over axle and straight out. No cats but here in VT on a 1990 car it isn't required. It does sound pretty amazing. The 226/238 .600 lift cam definitely aids that and the tbss intake is pretty good as far as stock intakes go. With a trunion kit and pushrods it made 390whp and 395wtq.
From the research I’ve done getting that “tuned” sound is all about making each side of the exhaust. 8-1 exhausts sound the best!!!! Or if you merge equal length headers immediately after the collectors into an c or Y pipe. Gives you a similar sound
I did the arithmetic for the exhaust headers in a Yamaha 900 bike engine. The originals were bang on the button so no surprise that free flowing mufflers made an obvious power improvement.
Just an edit to the x pipe explanation, the exhaust doesnt necessarily cross over, it mostly stays on the same side with a small amount of separation. The exhaust pulse hitting the point where they join does indeed help pull the exhaust from the other side. And for noise, an x pipe is an affordable substitute for equal length headers
I've done one full exhaust, I can't imagine tig welding it all tho. That takes some time! I had true dual xpipe and 2 Jones flowpacks. Rumbled the windows out of the house at idle and sounded super good when hammered down. Them xpipes just sound so good.
Man, I've listened to probably 40 different muffler sound videos on these trucks over the past couple of days. Trying to see what sounds best. Everything has this sluggish truck sounds to them and I have always hated the way they sound. But this one has that old school small block sound. It almost sounds like the DynoMax Ultra Flows I used to have back in the day. This is definitely how I want mine to sound when I build my 6.0 I'm saving this video for the future and I can stop listening now. But I've got to find your videos once it's driving and hear it and I got to find the dyno videos to see how it turned out. 💪
Super close to my 8.1l design on my burb. I did 3 sets of vbands. Stainless works long tube header to x pipe section, x pipe to Gibson dual 3" inlet, and the muffler to tail section. I'd post a photo but UA-cam won't let me.
Its nice to hear an exhaust system that brings out the sound of the cam unlike that straight pipe, too loud sound that everybody seems to be going for nowadays. It sounds good now but I bet it will sound great when the tailpipes are added.
I literally have the exact same set up on my 05 2500hd. Speed engineering long tubes, x pipe, to a y pipe into my flowmaster 4 inch hushpower muffler, and a dynomax 4 inch tailpipe. Only think I notice is that mine seems a touch louder then yours. Could be the difference between a 4.8 and a 6.0?
I’ve used C25 with TIG accidentally once. Wrong labels on two otherwise identical 250cf bottles. It burns up the tungsten very fast, especially on the sizes used on thinner material. I wouldn’t doubt it if that oxidized tungsten gets shot straight into the weld puddle either. So, no, it won’t work permanently. You’d be better off using the MIG on stainless than C25 TIG. Edit; Try it for yourself! As a hobbyist welder, I never even thought about it until that happened.
I recommend opening the ring gap for more boost. And that 4.8 will walk all over that 8.1L, obviously at higher rpm and only due to the LS design being much more stout, and can handle more boost.
Looks and sounds great! I just finished up a cam swap on my O6 5.3 and I need to do a setup like this! On a side note, this last cam I did I had the engine out and decided I was going to put the engine flat on its back and drop the cam in vertically and it worked awesome. Horizontally I always seem to scratch the cam bearings just a little no matter how hard I try.
thats the only way to do it for me. I've tried once or twice to do the sharpie mark and weld it outside the truck, but inevitably something moves around and wont line up properly. By clamping everything in place on the truck and getting 3-4 good tacks on each joint, you're pretty much guaranteed to have perfect alignment, which is critical when having 2 v-bands and no flex couplers.
Those 4.8s sound good! My buddy had one with shorty headers, stock exhaust to a chambered thrush muffler and a 5 inch tip. It was a mean little truck. This one sounds awesome with that cam! Good work with it!
Ps: I'm not an LS guru such as yourself, but have heard those 4.8 can really take some rpm with valve train mods. Next thing I need are some worked 799 or 243 heads to swap out my 706 for. The 706 we're rebuilt and the motor got new headgaskets and head studs. But aside from the cam, pushrods, pac 1219 springs it's all old junkyard motor internals. Has been abused pretty good it's first 5k and still holds 40psi of oil pressure. About 60 at cold start. PS wish I had your fab skills. I fabbed an air filter heat shield using license plates, some heat duct tape, and self tappers lol...
That was awesome. I was going to do that with my old IS350. Headers into a X pipe then into the ISF Y into a single huge 90mm muffler then out into the dual again after. Was told it would not work etc etc. but I found a guy who did just that and the X pipe made more torque from 2,000 to 5,000 by 2 - 3%. Engine Masters on MotorTrend did a full test on the X pipe with great results. The Y after if not restricted will add to the sound. Pretty cool exhaust build you did 😀👍
Look into the Gibson MWA muffler...and the Aeroturbine. The Aero tends to have a nice loud hollowy sound...and there XL series works awesome on reducing resonance on 4 bangers ..especially catless ones. The Gibson 5" race muffler on my Dakota 4.7...makes a massive difference in flow and the truck loves it. However...im considering switching to Corsa Pro Series. Same as you..im picky and have changed my Dakota exhaust about 9 times. Made my own larger collector into stock cat...directly into muffler...into Y pipe...to dual 2.5" lengths into stainless downturn tips. Also...anytime you do an exhaust...you should have about 18" of pipe after the muffler itself to accomodate its designed flow characteristics. An opened flanged at muffy will just disperse energy wildly and loose effectiveness. Happened on my exs Tahoe with flowmaster 10 series...they had a slip of paper directly stating this.
My Silverado came with a 4.8 and i just swapped the crankshaft and piston rods to convert it to a 5.3, since 4.8 have flat pistons i get a little more compression, add to the i swapped the 249 heads to 706 and they are cut for even more compression, swapped the cam for a BTR Torque Cam and deleted the VVT, had it programmed with HP+. I still need long tube headers and the x pipe but since im disabled and lost my job due to surgeries I ran out of money and the disability checks are minimal... So in hopes i do get better after all 3 surgeries and don't end up needing a 4rd surgery i hope im able to work again and finish my truck.
Sounds nice and mellow. Very similar to the 448 inch Arrington Hemi in my Chrysler 300S. I wanted a civilized sound in that daily driver and ended up with inch and seven eighth Stainless Works long tubes mated to high flow cats blowing into center mounted resonators with a balance pipe and stock rear mufflers. Car put down 562 HP to the tires with 554 LB FT and is almost as well mannered as the stock 5.7 engine that made 324 to the tires. It's a dream to drive and scary fast.
Finishing the length to go up over the axle and straight out will reduce the decibels. Right now, a lot of the sound will "reflect/bounce" off of the pavement and the truck bed, amplifying itself. I know from experience.
I did this to my 04 Gto as far as xpipe to ypipe. Mainly cause I didn’t want to put the dual exhaust like 05/06. It sounded good and I was happy with it
It sounds really good. Stapleton42 did an X pipe on his twin turbo Escalade and it sounds incredible. He ran flat out through a tunnel and the sound.......straight out of Talledega
That is a beautiful exhaust note. I have an 02 sport 5.9 magnum with a y-pipe and this might be a great addition to it when I put long tubes on the old girl.
To me, every slip connector is a chance for movement or an exhaust leak. It might just be personal preference, but I always build exhausts with as few clamped connections as possible
Hi LT NICE job on your truck 🚚 anyway the way that of the engine rumbling it reminds me of my late uncle 55 Chevy he had a 283 bored out to 301 11.1 compression he also used a camshaft from TRW in the day they didn't use the terms they use now they called it 3/4 so the cam you are using reminds me of that
Sounds and looks great. I figured being a truck you'd have more than enough real estate, but it was actually not as forgiving as I thought. You did a nice job of massaging those pipes through all those (somewhat) tight spaces. And it sounds just fine! Looking forward to the first ridealong...
Curious to know how a v8 would sound if the v8 is a single outlet header setup meaning it’s a single pipe no dual outlets.. what I’m curious is what if a Y pipe from a single into dual, then into a x pipe and two vibrant mufflers on both sides and dual back then a H pipe before it splits off to the back bumper.. always wondered what that would sound like. Logic can be used on any car that’s a single outlet header dump which are mainly sideways engines like fwd v8s v6s I4 etc etc…
Wish my welds looked as clean as yours! I’m learning to tig and I did some exhaust changes on my chevelle. It’s sealed up but doesn’t look very pretty. I may get your opinion on something. I had a 350 with a radical cam in a basically stock motor otherwise and It sounded awesome running through 70 series flowmaster mufflers with no H or X pipe, just simply cut about a foot before the rearend. I installed my race motor in it and then it sounded like crap no changes to the exhaust system. Sounded like it was beating the flowmasters with lots of ringing. I pulled them off and installed some Jones resonators with the large 10” body with 3” in and out. Now it sounds clean and mellow at idle but at 2500 rpm under throttle it sounds like tail pipes poppin. As if I have long 1” pipes out the back. It’s embarrassing! I would think 3” should be plenty of flow. What do you think?
I know this is an old video, but why the X pipe going into the Y pipe to one muffler? I was always told the X pipe is for two mufflers. The X pipe seems pointless in this setup. The Y pipe still joins the gasses before the muffler. If I've been taught wrong, please correct me.
Fuel the Al Gor ithm and support the RPM Act. When welding under the vehicle are you using a switch (2T/4T) or are you doing Jujitsu TIG welding and using your foot/knee/elbow.
Video never does justice but it sounds clean and meaty. I'm shooting for a similar effect/volume on my 95 stepside with a 454 swap. Longtubes, high flow cats, x-pipe, and a couple resonators. I'll leave space for a muffler but I've had good luck in the past by combining resonators.
4.8 is a destroked 5.3, i converted my 4.8 to 5.3 by just swapping the crankshaft and push rods, also i swapped the heads from i think they were 243 or 249 to 706 ported and cut for more compression, swapped the cam for a BTR Torque and had it programmed.
My question is when you need to drop that transmission oil pan to change fluid and filter are you going to have to take the exhaust apart? Cause it looks like the pipes are in the way of those pan bolts.
I assume the 4.8 is a V8 is that correct ? I would like to achieve the same sound out of my 4.3L V6. Would you email me the part numbers for the mufflers and cats. if you used cats? The OEM Single 2 into 1 exhaust on my S10 EXTREME was mostly 3" except for the Down pipe of the OEM exhaust manifolds and they were 2" ! I have a 2.25" exhaust pipes on it now that was suppose to be for an LS swap that never happened. (YET) Thanks Rod
You do good work welding. You should try walking the cup. It would help with the look of your stop starts. That's a great hood I've got the same one. Great video
cool concept but unless you have equal length runners going from the collector to the front of the x/y its kind of always going to have that signature "truck" sound
I have speed engineering headers and they are made of your standard cheap Chinese stainless (200 series)The flanges are Carbon steel and it then has been plated somehow. However I Cerakoted the headers and it seems to help.
I have a short bed Chevy been gone through small cam MSD coil but I just don't like the 40 series follow masters any suggestions I like the meatl sound of dulse 3 inch
Should have put a short 6-9" pipe on muffler outlet to straighten airflow out of muffler for more hp. 👍 Doing that also would get rid of some of the boomy drony sound, and would allow you to hear a bit more of the camshaft lope/chop.
I'm using that same Flowmaster y pipe. Y300400. Yeehaw. The y pipe won't stay black for long. You'll need to use some high temp paint on it once that burns off.
I like it. Reminds me of somewhere between a Coyote 5.0 and an old Mopar small block, it has a snappy growl to it and a little of that classic Mopar pop sound when it's coming back down. Still, 8.1 forever man. Maybe the 8.1 isn;t a race engine, but you can't explain how it feels driving one to someone that never has. The internet love peak HP on a dyno because you can't post of graph of driving experience. BTW, this video just popped into my feed out of nowhere. I'ma check out some of your other stuff now too.
Two 3's into a single 4 is not only matched for airflow, but is going to have a HELL of a lot of airflow. Great choice. Only bad thing I have to say is that THAT X doesn't have a whole lot of crossover compared to something like a Carven X. Now if you wanted something REALLY crazy, imagine this using a Borla Switchfire for the X. Also, the worst thing about trucks is that you can't have equal length downpipes coming to the X, which, I hear ruins the scavenging than an X gives you since it's no longer timed correctly.
I just hope this exhaust works as well as it sounds. So close to getting this thing on the dyno again.
I want that exhaust when you go turbo
21:06 man that sounds good. Would love to have that on my '88 c1500 with the 350

I did basically the same thing on my 5.8 windsor. 2 1/4 to a single 3” x 12” long resonator into a holley single inlet flowmaster with dual 2 1/2” out the back. Sounds similar to your truck. I love it.
The black widow muffler on my 5.3 LS has a dual 3" inlet and single "3 outlet. It has 1 7/8 headers with vbands to an x pipe similar to the one you show. (May even be the same). So after the x pipe it has a 30" dual straight section to the black widow dual to single. With another vband flange on the outlet. Has a single 3" over axle and straight out. No cats but here in VT on a 1990 car it isn't required. It does sound pretty amazing. The 226/238 .600 lift cam definitely aids that and the tbss intake is pretty good as far as stock intakes go. With a trunion kit and pushrods it made 390whp and 395wtq.
For a little 4.8l and single pipe out, that sounds tough as! Nice job. Love the sound and hope it lays down the HP you're hoping for.
Any suggestion where to look for a dual exhaust kit for a 2000 suburban would you
From the research I’ve done getting that “tuned” sound is all about making each side of the exhaust. 8-1 exhausts sound the best!!!! Or if you merge equal length headers immediately after the collectors into an c or Y pipe. Gives you a similar sound
Sounds great! I just finished a 2 into 1 on my 69' mustang with a 4.6 32v and I love the sound. Just 2 1/4 to Y to 3" single chambered muffler.
I did the arithmetic for the exhaust headers in a Yamaha 900 bike engine. The originals were bang on the button so no surprise that free flowing mufflers made an obvious power improvement.
Just an edit to the x pipe explanation, the exhaust doesnt necessarily cross over, it mostly stays on the same side with a small amount of separation. The exhaust pulse hitting the point where they join does indeed help pull the exhaust from the other side. And for noise, an x pipe is an affordable substitute for equal length headers
I've done one full exhaust, I can't imagine tig welding it all tho. That takes some time!
I had true dual xpipe and 2 Jones flowpacks. Rumbled the windows out of the house at idle and sounded super good when hammered down.
Them xpipes just sound so good.
Dude you are a freak of wrenching. You turn the videos out quick. Love the content. Please keep it up
appreciated! Got plenty more content to come!
Man, I've listened to probably 40 different muffler sound videos on these trucks over the past couple of days. Trying to see what sounds best. Everything has this sluggish truck sounds to them and I have always hated the way they sound. But this one has that old school small block sound. It almost sounds like the DynoMax Ultra Flows I used to have back in the day.
This is definitely how I want mine to sound when I build my 6.0
I'm saving this video for the future and I can stop listening now. But I've got to find your videos once it's driving and hear it and I got to find the dyno videos to see how it turned out. 💪
Super close to my 8.1l design on my burb. I did 3 sets of vbands. Stainless works long tube header to x pipe section, x pipe to Gibson dual 3" inlet, and the muffler to tail section. I'd post a photo but UA-cam won't let me.
Its nice to hear an exhaust system that brings out the sound of the cam unlike that straight pipe, too loud sound that everybody seems to be going for nowadays. It sounds good now but I bet it will sound great when the tailpipes are added.
I literally have the exact same set up on my 05 2500hd. Speed engineering long tubes, x pipe, to a y pipe into my flowmaster 4 inch hushpower muffler, and a dynomax 4 inch tailpipe. Only think I notice is that mine seems a touch louder then yours. Could be the difference between a 4.8 and a 6.0?
I’ve used C25 with TIG accidentally once. Wrong labels on two otherwise identical 250cf bottles.
It burns up the tungsten very fast, especially on the sizes used on thinner material. I wouldn’t doubt it if that oxidized tungsten gets shot straight into the weld puddle either.
So, no, it won’t work permanently. You’d be better off using the MIG on stainless than C25 TIG.
Edit; Try it for yourself! As a hobbyist welder, I never even thought about it until that happened.
I recommend opening the ring gap for more boost. And that 4.8 will walk all over that 8.1L, obviously at higher rpm and only due to the LS design being much more stout, and can handle more boost.
Already opened em up, she’s ready for the boost!
@@LawrenceTolman well heck ya man. Sorry i must have missed that information.
Dang, I wasn't expecting that. That idle is chef's kiss
Looks and sounds great! I just finished up a cam swap on my O6 5.3 and I need to do a setup like this!
On a side note, this last cam I did I had the engine out and decided I was going to put the engine flat on its back and drop the cam in vertically and it worked awesome.
Horizontally I always seem to scratch the cam bearings just a little no matter how hard I try.
That exhaust sound is for me too, damn I wasn't expecting it to sound so good. Nicely done, sir!
I like the way you use material clamped to the truck to keep parts of the system positioned correctly to the vehicle. Sounds great!
thats the only way to do it for me. I've tried once or twice to do the sharpie mark and weld it outside the truck, but inevitably something moves around and wont line up properly. By clamping everything in place on the truck and getting 3-4 good tacks on each joint, you're pretty much guaranteed to have perfect alignment, which is critical when having 2 v-bands and no flex couplers.
I guess that pipe is male then
How does this only have 5 likes that's gold
LMAO
Hahaha
Good one LMFAO 😂😂😂
Underated comment 😹
First of these videos I’ve seen. That exhaust setup sounds incredible!! You can REALLY hear that cam, love it!!
perfect mixture between a crackle and a rumble sound! excellent! very clean looking work!
Those 4.8s sound good! My buddy had one with shorty headers, stock exhaust to a chambered thrush muffler and a 5 inch tip. It was a mean little truck. This one sounds awesome with that cam! Good work with it!
Ps: I'm not an LS guru such as yourself, but have heard those 4.8 can really take some rpm with valve train mods. Next thing I need are some worked 799 or 243 heads to swap out my 706 for. The 706 we're rebuilt and the motor got new headgaskets and head studs. But aside from the cam, pushrods, pac 1219 springs it's all old junkyard motor internals. Has been abused pretty good it's first 5k and still holds 40psi of oil pressure. About 60 at cold start.
PS wish I had your fab skills. I fabbed an air filter heat shield using license plates, some heat duct tape, and self tappers lol...
Geez - that is the best sounding muffler ever. Sounds like an off-shore racer.
That sounds amazing, LT. This whole build has been great.
That was awesome. I was going to do that with my old IS350. Headers into a X pipe then into the ISF Y into a single huge 90mm muffler then out into the dual again after.
Was told it would not work etc etc. but I found a guy who did just that and the X pipe made more torque from 2,000 to 5,000 by 2 - 3%.
Engine Masters on MotorTrend did a full test on the X pipe with great results. The Y after if not restricted will add to the sound. Pretty cool exhaust build you did 😀👍
hey thanks! I was a little nervous about how the X into Y would sound, but once I started it up, I was pleased!
Look into the Gibson MWA muffler...and the Aeroturbine.
The Aero tends to have a nice loud hollowy sound...and there XL series works awesome on reducing resonance on 4 bangers ..especially catless ones.
The Gibson 5" race muffler on my Dakota 4.7...makes a massive difference in flow and the truck loves it. However...im considering switching to Corsa Pro Series.
Same as you..im picky and have changed my Dakota exhaust about 9 times. Made my own larger collector into stock cat...directly into muffler...into Y pipe...to dual 2.5" lengths into stainless downturn tips.
Also...anytime you do an exhaust...you should have about 18" of pipe after the muffler itself to accomodate its designed flow characteristics. An opened flanged at muffy will just disperse energy wildly and loose effectiveness. Happened on my exs Tahoe with flowmaster 10 series...they had a slip of paper directly stating this.
You absolutely nailed it me and my son love the custom exhaust you made 4 inch is great on v8 , it has the same area of volume plus velocity!!!!!!!!!
I got speed engineering headers on my 4.8 with the x pipe kit and 2 glasspacks for now. Sounds great but I want mini bullets and a boom tube
Awesome JOB DY NICE TONE JUST RIGHT NOT TOO LOUD AND OBNOXIOUS BUT DEEP AND AUTHORITIVE NO POPING NAILED IT
My Silverado came with a 4.8 and i just swapped the crankshaft and piston rods to convert it to a 5.3, since 4.8 have flat pistons i get a little more compression, add to the i swapped the 249 heads to 706 and they are cut for even more compression, swapped the cam for a BTR Torque Cam and deleted the VVT, had it programmed with HP+. I still need long tube headers and the x pipe but since im disabled and lost my job due to surgeries I ran out of money and the disability checks are minimal... So in hopes i do get better after all 3 surgeries and don't end up needing a 4rd surgery i hope im able to work again and finish my truck.
Sounds nice and mellow. Very similar to the 448 inch Arrington Hemi in my Chrysler 300S. I wanted a civilized sound in that daily driver and ended up with inch and seven eighth Stainless Works long tubes mated to high flow cats blowing into center mounted resonators with a balance pipe and stock rear mufflers. Car put down 562 HP to the tires with 554 LB FT and is almost as well mannered as the stock 5.7 engine that made 324 to the tires. It's a dream to drive and scary fast.
If you're are TIG welding keep with the Argon 75/25 might mess up your weld
Finishing the length to go up over the axle and straight out will reduce the decibels. Right now, a lot of the sound will "reflect/bounce" off of the pavement and the truck bed, amplifying itself.
I know from experience.
I thought that was a 8.1 when I heard it. Huge pipes for a little motor! I love it!
I did this to my 04 Gto as far as xpipe to ypipe. Mainly cause I didn’t want to put the dual exhaust like 05/06. It sounded good and I was happy with it
It sounds really good. Stapleton42 did an X pipe on his twin turbo Escalade and it sounds incredible. He ran flat out through a tunnel and the sound.......straight out of Talledega
I bet that does sound killer!
That is a beautiful exhaust note. I have an 02 sport 5.9 magnum with a y-pipe and this might be a great addition to it when I put long tubes on the old girl.
At 7:43, why don't you like slip fit connections LT? Its' one joint less to weld but I'm not an exhaust builder. Please let us know!
To me, every slip connector is a chance for movement or an exhaust leak. It might just be personal preference, but I always build exhausts with as few clamped connections as possible
Sounds good, I honestly think a LTH to X pipe to Dyna Tech split flow is the meanest sound I've gotten from an LS engine.
I'll have to look into that one!
Hi LT NICE job on your truck 🚚 anyway the way that of the engine rumbling it reminds me of my late uncle 55 Chevy he had a 283 bored out to 301 11.1 compression he also used a camshaft from TRW in the day they didn't use the terms they use now they called it 3/4 so the cam you are using reminds me of that
Sounds and looks great. I figured being a truck you'd have more than enough real estate, but it was actually not as forgiving as I thought. You did a nice job of massaging those pipes through all those (somewhat) tight spaces. And it sounds just fine! Looking forward to the first ridealong...
Good stuff man. You're getting so much better at this youtube thing LT. Keep it going im here for the long haul!
LS ended in 2014 and LT1 came in. Was has its pros and cons but I have a 2016 and never thought of going to LS 🤷🏼♂️ changed my 5.3 to 6.0
Curious to know how a v8 would sound if the v8 is a single outlet header setup meaning it’s a single pipe no dual outlets.. what I’m curious is what if a Y pipe from a single into dual, then into a x pipe and two vibrant mufflers on both sides and dual back then a H pipe before it splits off to the back bumper.. always wondered what that would sound like. Logic can be used on any car that’s a single outlet header dump which are mainly sideways engines like fwd v8s v6s I4 etc etc…
Sounds good LT. Need to replace exhaust on my 7.4 I wonder how this setup would sound on a bbc
would probably sound pretty similar to this honestly.
People are always digging on the 4.8’s but they are tough and just as good as a 5.3 imo
4.great
There’s almost no difference in performance, just a tad more torque with 5.3 and that’s it
@@eternalthread7846it’s quite a difference with the torque
It sounds so awesome! This truck sure has come a long way! Love it
How about kooks Long Tube Headers with Flowmaster Series 10 straight Pipes Dumped before the axle
Wish my welds looked as clean as yours! I’m learning to tig and I did some exhaust changes on my chevelle. It’s sealed up but doesn’t look very pretty. I may get your opinion on something. I had a 350 with a radical cam in a basically stock motor otherwise and It sounded awesome running through 70 series flowmaster mufflers with no H or X pipe, just simply cut about a foot before the rearend. I installed my race motor in it and then it sounded like crap no changes to the exhaust system. Sounded like it was beating the flowmasters with lots of ringing. I pulled them off and installed some Jones resonators with the large 10” body with 3” in and out. Now it sounds clean and mellow at idle but at 2500 rpm under throttle it sounds like tail pipes poppin. As if I have long 1” pipes out the back. It’s embarrassing! I would think 3” should be plenty of flow. What do you think?
I know this is an old video, but why the X pipe going into the Y pipe to one muffler? I was always told the X pipe is for two mufflers. The X pipe seems pointless in this setup. The Y pipe still joins the gasses before the muffler. If I've been taught wrong, please correct me.
Sounds great. The real trick is to eliminate the drone. Magnaflow makes a 3" DI/DO w/internal X that is known to be good for that.
Fuel the Al Gor ithm and support the RPM Act.
When welding under the vehicle are you using a switch (2T/4T) or are you doing Jujitsu TIG welding and using your foot/knee/elbow.
I still use the pedal, just keep my knee bent up and it works good for me
Man this sounds really great and nice work on the exhaust build!!
Video never does justice but it sounds clean and meaty. I'm shooting for a similar effect/volume on my 95 stepside with a 454 swap. Longtubes, high flow cats, x-pipe, and a couple resonators. I'll leave space for a muffler but I've had good luck in the past by combining resonators.
4.8 is a destroked 5.3, i converted my 4.8 to 5.3 by just swapping the crankshaft and push rods, also i swapped the heads from i think they were 243 or 249 to 706 ported and cut for more compression, swapped the cam for a BTR Torque and had it programmed.
are u using a Stainless Steel brush on ur welds? I know it's more evpensive but an Argon purge would be nice...
Sounds great i just got a 08 with the 4.8 & I'm doing a Texas speed stage 2 cam and then I'm going to have to find out how to get it tuned..
My question is when you need to drop that transmission oil pan to change fluid and filter are you going to have to take the exhaust apart? Cause it looks like the pipes are in the way of those pan bolts.
I assume the 4.8 is a V8 is that correct ? I would like to achieve the same sound out of my 4.3L V6. Would you email me the part numbers for the mufflers and cats. if you used cats? The OEM Single 2 into 1 exhaust on my S10 EXTREME was mostly 3" except for the Down pipe of the OEM exhaust manifolds and they were 2" ! I have a 2.25" exhaust pipes on it now that was suppose to be for an LS swap that never happened. (YET) Thanks Rod
You absolutely nailed 👏 that exhaust. Sound ground clearance and it don't look bad. Keep up the great work 👍
You do good work welding. You should try walking the cup. It would help with the look of your stop starts. That's a great hood I've got the same one. Great video
cool concept but unless you have equal length runners going from the collector to the front of the x/y its kind of always going to have that signature "truck" sound
Just stumbled on this page after wathing my usual Samcrac and Legit Street Cars. Very cool! Subscribed!
Thanks for the sub! LSC has some great builds!
Dumb question but my 5.3 vortec v8 engine on 2007 GMC Sierra isn’t a LS right? Cuz he mentioned 5.3 and 6.0
Of course it is, 4.8, 5.3, 5.7, 6.0 and 6.2 from 97 to 13 (kinda) are part of the LS family
@@9502silverado And the 7.0 from the Z06.
@@JimFlanagan4206 yes and no, the ls7 is almost it’s own thing..
@@JimFlanagan4206 yea definitely ls based but like Matt said, it's kinda its own thing
I have speed engineering headers and they are made of your standard cheap Chinese stainless (200 series)The flanges are Carbon steel and it then has been plated somehow. However I Cerakoted the headers and it seems to help.
Sounds exactly how I want my Hemi Jeep to sound!! Great job!
I have a short bed Chevy been gone through small cam MSD coil but I just don't like the 40 series follow masters any suggestions I like the meatl sound of dulse 3 inch
Should have put a short 6-9" pipe on muffler outlet to straighten airflow out of muffler for more hp. 👍
Doing that also would get rid of some of the boomy drony sound, and would allow you to hear a bit more of the camshaft lope/chop.
Sounds absolutely amazing I’ve been thinking of a similar set up on a v8 over here in U.K. so now I’m going to mark one 👍🏻😁
I'm using that same Flowmaster y pipe. Y300400. Yeehaw.
The y pipe won't stay black for long. You'll need to use some high temp paint on it once that burns off.
I like it. Reminds me of somewhere between a Coyote 5.0 and an old Mopar small block, it has a snappy growl to it and a little of that classic Mopar pop sound when it's coming back down.
Still, 8.1 forever man. Maybe the 8.1 isn;t a race engine, but you can't explain how it feels driving one to someone that never has. The internet love peak HP on a dyno because you can't post of graph of driving experience.
BTW, this video just popped into my feed out of nowhere. I'ma check out some of your other stuff now too.
Two 3's into a single 4 is not only matched for airflow, but is going to have a HELL of a lot of airflow. Great choice. Only bad thing I have to say is that THAT X doesn't have a whole lot of crossover compared to something like a Carven X.
Now if you wanted something REALLY crazy, imagine this using a Borla Switchfire for the X.
Also, the worst thing about trucks is that you can't have equal length downpipes coming to the X, which, I hear ruins the scavenging than an X gives you since it's no longer timed correctly.
