the MOST INCREDIBLE sounding exhaust EVER! 4.8 vs 8.1 shootout Pt.9
Вставка
- Опубліковано 28 тра 2024
- It's time to build an exhaust system on the 4.8 Silverado since open headers on a cammed LS isn't exactly streetable. For the exhaust I wanted something that would perform great both now and when the power adder gets installed, but also sound unique at the same time. This required at least 3" exhaust for the single dual sections, and 4" for the single section. I wanted to use one of my favorite mufflers of all time, the Flowmaster Hushpower Pro Series 4" but I had no idea how it would sound with both an X pipe and a Y pipe.

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 ran mufflers and turn downs on my lowered 3500 7.4l dually for years, finally built full tailpipes and it completely changed the sound! Thankfully for the better. I can't wait to hear your 4.8 when its finished.
I've always wanted to do this but never found anyone who has untill now 👍👌
You’ve got mail sir... Via Facebook messenger
Finally! Someone who understands and shares the knowledge of exhaust pulses, scavenging, and the carrying the flow through a set of convergent and divergent points. 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!
I’m also an outcast in my area. Exhaust is my favorite part of automotive engineering. I love the science and madness behind it.
I have my stock H pipe connected to a custom x pipe in my exhaust sounds awesome
Exhaust note sets the entire tone of the car... especially if you hear it before you see it.
@@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.
Yo so if I have a 04 Mustang GT, what setup should I get if I want it ridiculously loud??
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.
The older CJ5 Jeep with an I6 could be had at a curb weight, 1000lbs lighter. Still a jeep and plenty quick for time.
@@JPGenergy haha I bet all the neighbors loved him
This is hands down the best LS I've heard in YEARS!!!!!! You NEED to give us a 10 min video of just exhaust sounds when this thing gets on the road. You knocked this one out of the park🔥🔥🔥🔥
Hey now! Let's not beat up on Sloppy's hood dump 🤣 I always cry a little for any motor with zoomies.
Hey thanks! I wanted different and I think it’s for sure that.
yeah LS motors usually sound very tinny and raspy.
@@OEMPlus especially ones with X's
@@LawrenceTolman does it have a lot of drone? I have a 8.1 your the only one to put a video up with this muffler!
Love this whole build series. That tiny 4.8 sounds fierce.
Bigger than a Terminator Cobra. At that displacement I’d take the DOHC though. =^D
@@snappyaj9053 Luckily you can go up to (and over) 7.0L and the block is nearly the same externally.
tiny?
@@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.
@@Superthecod yeah it's only 293 cubic inches of displacement
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, 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.
This sounds excellent, not raspy or tinny rather has what I call an honest V8 sound, deep and throaty. Great job!
Absolutely Incredible!!!! and I am an older guy! That sound makes my soul sing and my heart happy!! Dude, mad respect for this guy to leave his "professional" gig to start this awesome channel and forging his own road. LT you are my hero!!
hey thanks for watching! I am thankful that I have the opportunity to give this a shot.
That cam chop sounds really good! I gotta go that route when I start my wife's truck build.
Thank you so much for starting this channel! It's great to see what can be done in a basic garage, with basic tools, and a realistic-ish budget vs a full shop and equipment with sponsored products that essentially bolt on. I have learned enough to get myself broke, or in trouble from the big budget shows. Showing how you are able to improvise without fancy equipment has taught me far more. Thank you so much for everything you do to keep this a fun and realistic hobby without needing to win the lottery.
hey thanks! its fun to be able to work in those no-budget type shops, but far more relatable to be able to do it on your own as well. Thanks a ton for watching!
It's amazing what you do crawling on your back. I've done exhaust work and without a lift it's basically a waste of time... But you're still able to work magic. Hoping you get big so you can get a shop with a lift and really churn out the work.
I 2nd this exhaust work on your back sucks so much ass, I swapped a muffler on my sonoma just with the stock piping and I hated it so much lmao
Hey thanks! It’s sure a pain, but it’s better than working in a gravel driveway like I did growing up lol
Lt your a Sav. And what makes you a real one, is gettin it done with what you have and movin up with time/hard work like most of us goin from a cherry picker in apt. parking lot/dirt gravel drive way to your own garage and on.
@Devin Herrington A harbor freight foam creeper works great for that! 😁
Such a clean deep sound, no popping whatsoever when you let off the accelerator amazing.
the pop at the end is akin to the satisfaction of an orgasm to me so cant relate.
perfect mixture between a crackle and a rumble sound! excellent! very clean looking work!
That sounds amazing, LT. This whole build has been great.
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.
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!
Sounds great, would love to hear it with a tailpipe !
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!!
Sounds A LOT better than I thought it would!
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!
It sounds so awesome! This truck sure has come a long way! Love it
Man this sounds really great and nice work on the exhaust build!!
You absolutely nailed 👏 that exhaust. Sound ground clearance and it don't look bad. Keep up the great work 👍
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...
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!
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
glad you found the channel as well, and thanks for the kind words!
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
Always loved 180's. Lots of circle track guys use them.
That exhaust sound is for me too, damn I wasn't expecting it to sound so good. Nicely done, sir!
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.
Love the slip fit design of those v bands
Love the attention to detail! Great work!
I've been watching you for years. Way b4 u got on UA-cam. You just take great pride in everything you do , it's very easy to cut corners , especially on ur personal rides. But not gonna happen Great job man. I'd love to just send my truck to you and say here you go lol. Thanks for posting
Thanks for watching both here and before, much appreciated!
Good stuff man. You're getting so much better at this youtube thing LT. Keep it going im here for the long haul!
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.
Wow, wow, wow. That is awesome! It's perfect even though I am partial to the Flowmaster Super 40 series chambered muffler sound. I like how you used those exhaust parts together. Definitely a racy aggressive sound.
Sounds great!!! Your passion shows in your work.
Awesome!!!! I need something like that for my 8.1
Man that exhaust is gorgeous. Always such a pleasure to see quality work vs. the hackery from a channel like Exhaust Addicts.
Much appreciated!
What's wrong with Exhaust Addicts? Sure they don't always post bangers but not every customer has a good sense of taste. You can't blame them for customers having terrible taste
@@iraqifoodcart8447 Has nothing to do with the cars. They slap up their garbage on nice cars too. Dude you seriously can't look at the garbage quality booger welded steel straight pipes they put on everything and think that shit look ok lol. Looks like Stevie Wonders first day on the job with a Mig welder. I wouldn't put that crap on a beater, nevermind a nice car.
Sounds mega!
Great job as always LT
Dang, I wasn't expecting that. That idle is chef's kiss
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.
Sounds good. If I ever change out my 10-series 1-chamber Flowmasters I might try those.
Sounds great. Nice work as always.
I love it , I plan on doing something similar on my 02 5.3
Your exhaust work is great. It also sounds amazing.
Sounds awesome! Outstanding work Sir
Sounds amazing! This will be great with that hd front end on this rig
Damn. Best sounding 4.8 I’ve heard. Great video and lots of good info. Subbed 👍
Sounds great LT, nice chop, good tone.
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
Thank you for the details and congrats on a beautiful exhaust!! Man that sounds amazing and my tiny phone speaker does no do justice I’m sure.
I too am very particular on the exhaust note I desire. I want so I’m struggling trying to find a system but I can’t weld so I’m looking for a system to assemble myself.
Man I love the way that set up sounds
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.
Yup you’re satisfied with this sound! I can tell because you can barely talk, because you’re grinning ear to ear. It’s well deserved. Excellent work
I agree 👍🏻 sounds amazing
Awesome JOB DY NICE TONE JUST RIGHT NOT TOO LOUD AND OBNOXIOUS BUT DEEP AND AUTHORITIVE NO POPING NAILED IT
Would love to see a side by side cold/warm start with the exhaust as it sits and with the back half disconnected. Great video!
I have the most discerning ear and very seldom like how most exhaust systems sound, that said, this truck sounds absolutely awesome! Great work LT.
Glad I got your vote of approval! I love how this one sounds
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
Exhaust system came out really nice. 👍🏻
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.
Wow nice job sounds great!! Can’t wait to see dyno numbers
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
I effing love the noise, thnx!
Nice job on the exhaust! Not only spending the time to make it fit and look good but engineering it to be easy to remove later.
Love ALL the things you've done to these trucks - wondering what my 4.3 Silverado wld sound like with a modified exhaust - I had an older 4.3 Silverado yrs ago that didn't sound too bad with duals - but it was doggy - thanks LT for spreading the knowledge 🤘
Sounds good, nice work!
Sounds great! Congratulations.
Sounds great!
Love this series
Sounds beautiful!
SOUNDS GREAT THANKS FOR SHARING
Congrats LT, sound awesome.
Keep going Boy
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 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 thought that was a 8.1 when I heard it. Huge pipes for a little motor! I love it!
The exhaust sounds great! Nice rumble but not too loud. Hope the 4.8 makes some good numbers once you get it back on the dyno. Thanks for the video!
I think I know how im running my next exhaust setup. sounds sick
Just found your channel.
Glad I did. I actually really like the sound of your truck
Thanks for checking it out!
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!
LT, I enjoyed watching the way you build an exhaust system, good video. I will be building one soon for my roadrunner but with mig only because that's what I have. Thanks for the good tips when designing n building.
Glad it was helpful!
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!
Sounds exactly how I want my Hemi Jeep to sound!! Great job!
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.
love the way it sounds bud good job
That sounds really good man.
Sounds badass! Hoping I can get my truck to sound just as good someday!
Sounds awesome great work
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!!!!!!!!!
sounds great looking forward to here it turned up.
You and me both!
I love this I really want to make this exhaust been on my mind to do an x and a y pipe for an eg33
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 👍🏻😁
That sounds amazing!
Wow that sounds fantastic. Especially for a 4.8
Agree, sounds really good.
Sounds bloody awesome
That sounds awesome ! Good job .
loved Project red tide exhaust......this one sounds pretty awesome as well
I liked how that one looked, but sadly it sounded too plain.
It really sounds amazing
