Double X pipe added, and it's still clapped out 😂
I like clappy exhausts.
That's cause x pipes don't do what he's claiming they do. They usually just make it more high pitched. What he needs is back pressure, muffling or resonating. So unless the x shaped pipes are resonated they won't do shit to improve the sound.
@@FirstnameLastname-pe5ibH pipes give you better low end torque, X pipes perform better in the higher rpm range.
@@FirstnameLastname-pe5ibAgreed. A resonated h pipe on my catback made a huge difference
@@GrumpyMonkey69 Im aware. But adding another won't improve power. And if it's non resonated it will NOT improve the sound whatsoever.
"no more clap!" as the truck is clapping like all fuck
I wanna see 5 x pipes back to back the whole way
😂😂😂😂😂
1000$ 😂 for that
Me too
Gonna lose 5hp lol
Garage54 will make the whole thing X front to back. They will do almost anything
Sounds exactly the same to me. Throw a resonator on if he wants to kill some decibels.
The louder the better screw making a truck quite if it’s quite its not a truck
A single Magnaflow dual in/out muffler with a built in x-pipe would've been more simple and gotten rid of all the clapping, so it sounds like a grown up truck.
I don't recommend those Magnaflow "Tru-X" resonator/x-pipe combos. X-pipes need high-velocity, smooth-flowing exhaust pulses, because those pulses need to pass straight through the crossover without expanding out into the other pipe, which would slow it down, increasing backpressure, reducing scavenging, and thus completely defeating the sole purpose of the x-pipe. Muffling harsh frequencies and drone is the sole purpose of resonators and mufflers. You can certainly build a resonator by sticking a heavily perforated x-pipe into a muffler case full of packing and/or baffle chambers. That muffles the sound by intentionally diffusing exhaust gases into the case's larger volume, which slows them down, and usally forces them through obstacles to further reduce the gas velocity before they exit the tailpipe. That might be an excellent design for a resonator or muffler, but it's a terrible design for an x-pipe that needs high exhaust velocity to function. Why compromise when you can just install one proper x-pipe near the headers, then add a pair of short bottle-style resonators downstream and have the best of both worlds?
"No more clap" *brapapap in the background*
It took all the rasp out? Now I'm wondering how raspy it was before, because that's still raspy as hell 🤣
Feel sorry for whoever has to cut that exhaust out of the way to remove transmission in the future😊
Junky Dodge trans need replaced every 30,000 miles?
More labor to charge lol
dont be so dumb.i got 375k on my 2000 dakota and it still runs perfectly
probably talking 2007 to present. cylinder deactivation kills lifters and trans@@Bigguy4778
Why cut it when you can unbolt it at the collector? 🤔
Did exhaust professionally for 4 yrs, and I would have put a dual in/out Flow master Super 40 where the second x-pipe is and never had all that crazy rasp sound and still sound like a big boy truck, no x-pipe needed.
It doesn't need to be above 93db @50ft away from the truck unless your customer wants to get a ticket for noise.
Flowmaster junk
@@Southized lol, unpopular opinion I know, it did get me lots of vehicles from more than 100 miles away tho..........🤔
@@Mr._Flunky i never like flowmaster sound cheap sounds like soda can or in a tunnel hard to describe they all sound same
Might as well not even get your exhaust done at that point.
Flowmaster sounds great outside of the truck. In the cab cruising is nothing but drone. And yes even the super 40/44 does it. I've tried both of them. That's why I switched to Black widow venom 250 w/no cats. Sounds great and zero drone in the cab. They're also stainless
I've always wanted to see what a fully braided exhaust looks and sounds like
The un-equal length pipes are also adding to the clap.
These guys clearly don't understand sound waves
X equals everything out power + efficiency makes exhaust work together by one pulse pulling the next
@@bayarearaised1894yeah lol I think they are clapped
It sounded good at idle, sounded good when you revved it up, but when it drove down the road, it clapped like a Carolina squatter
Straight pipe was good but H pipe would have sounded more mellow...
X2 on the h pipe
H pipe makes it sound more muscular
H equals out exhaust pressure for better torque.X makes exhaust pulses pull each other out for more HP.
Sounds like he's using Mexican food for gas.
Be nice 20 alphabet, I love me some Mexican food.....
😂😭
Out of all your vids, this is possibly the most impressive. It shows you guys REALLY do know your stuff. DEFINITELY bringing business from Oklahoma your way!!
Wow, thanks!
lol gullible, dual x pipes don’t do anything more than single, a true exhaust fanatic knows the equation to determine how far from the collectors to place a j tube, for softening the scavenging pop. There’s no such thing as a double helix sound, double helix is a visual like a dna pattern.
@@feellnfroggyj pipe doesn’t add power x does so if some power can be added along with sound reduction why not. Also j pipe is more for drone not rasp. X equalizes everything
@@utahcountypicazospage5412 not true at all. I've had both x and offroad h pipes and neither helps rasp in v6 or V8 . And I'm currently running a pro chamber on a 4 valve with resonators. That don't help either. The j pipe at the right distance is what helps arrest the pops associated with the"buzz". Due to the type of cranks we run. Either j pipe or equal lengths 8 into one headers built right.
@@feellnfroggy agreed on the j pipe setup, have done that few times to kill drone on highway. Just bc you have a welder and pipe bender doesn't make you good at exhaust lol talking about the shop not you.
It sounds better with the two X's
Reminds me of them german v8's, C63 AMG and the likes. Sounds absolutely lovely.
To remove the classic truck sound, you need to equal length it. Differences from a Ram exhaust and a Durango exhaust
I don't know where most of the people come from who watch your videos but it's not Oklahoma we like our cars loud. Because we feel the same way a Harley rider feels loud pipes save lives.
I love your guys work. I need to bring my Chevy dually over and have you guys redo it.
SO much better with the double xover, but it just sounds incredibly choked. Did you suggest replacing the cats? I'd think that would be a super easy upsell for folks bringing in older vehicles.
Based on that year 4.7 if youre stock power levels then trying to get it to have higher RPM flow isnt worth it, they dont spin higher than 5800rpm even at that after about 5500 you can feel it running out of steam. The stock exhaust valves are 1.46" Manifold primaries are only 1-1/2" so basically the same size as the exhaust valve, so dual 2.25 or single 2.5 is the best and the OEM Y collector outlet is 2.5" Unless youre pushing 300+ horses then dual 2.5" OEM Dodge cats of that era were already "high flow" so as long as you got the identical ones or a less dense honey combed core like they are from factory.
It just doesnt sound as good under load without a muffler leeast when they straight pipe dual them. Idle is fully chonky and deep, but under load is like a wet fart/clap noise
They say anything sounds good just to get that money 🤣
whats the sound if a large center pipe is shared, like a 5" pipe?
Jesus, that would be too loud for me too. Sounds better with the xpipe but I think there's a lot of room for improvement still.
My buddy had the crew cab version, we did a single pipe, with 1 Magnaflow performance with an exit in front of the RR wheel. It sounded great, the cop even complimented it the next day, (Buddy was speeding, cop heard him coming, lol.) Now it sounded really nice without costing a lot. The other mod was pulling the wire from the TCM. That wire changes timing before a shift. Without that wire hooked up the truck became fun. Have a transmission on standby. Since then I've been looking for a cheap Dakota with a 4.7.
It’s still clappy, still outrageously loud, should have just done a crossover way forward where they’re supposed to be and tossed a couple mufflers on and boom it sounds good at a decent volume
Got a new subscriber....this taught me that a dual crossover will sound great on my Bronco. Gonna do an H pipe cause its easier with the setup i gotta do, and then a Dynomax UltraFlo X muffler.....so true duals with 2 crossovers....
I may finish it off at the end with two Black Widow "Neighbor Haters" before the tips.
"I removed the muffler and can't figure out why it's soo loud and obnoxious."
I have the quad cab version ...I used a single in/out Corsa Pro Series ...short muffler as an x-pipe under the passenger floor where theres a ton of room. I have ZERO drone....insane flow, and very tolerable raps and pops that are fun.
Wow. Wish he could've revved it some more.
I wonder how it would change if you out an x towards the front and one closer to the rear. Maybe even 3 of them
I got 3 on mine. They not spread apart, so idk how much different it would sound if they were spread out. But 3 can definitely tone down the vehicle
The straight pipe, nah, sounds like yuk. The double x pipes have a nice rumbling sound IMO.
The double x cleans it up a lot..
The background traffic noise is louder than anything
I always like engines screaming high rpm style. To me this isn't for me. But the FedEx part got me.
double X pipe with a 3in exhaust would have sound better and less clappy.
I did this to my q50 redsport. 2 x pipes vibrant resonators hks high power mufflers out 2 cannons with 2 hidden turn downs
Don't forget to try an 8-2-1 system using a "Y"
its less raspy with double X pipes, but if he really wanted to go further, adding resonators would do the trick. it'll still be loud but refined.
I like how quiet the double x pipe gets.
thought the x pipe was supposed to be placed about a foot or so away from the header collector for best scavenging results…
I went straight 3" duals on my 5.3 and ended up with an x pipe and 2 flowmasters. It was so loud when I would pull out on the interstate, road crew a mile away all turned to look, thats when I knew it was too loud.
The slowest trucks always seem to be the loudest.
Dual in dual out original 40 series would've been great
Everyone runs them and FM, Cherrybomb and a few other classics are made in China...
Nice job. But way too loud for a daily driver. I think the H pipes sound better than the X pipes. But they both sound and perform better than just true duals. Thanks for the videos.
Fair enough!
Do y’all install headers?
Double X-pipe sounds much, much better, but I probably would’ve opted for an H-pipe and resonators.
Heres what i do. I bring them together with a Y pipe. Then, split them again with an h pipe. But right before the rear axel? Boom. Criss cross apple sauce with the x pipe.
The triple threat.
you ever done a double H on a 3.6 pentastar dodge charger? curious to hear what that sounds like.
Sounds the same to me
Dump the x-pipes and put in two two and a half inch offset 40 series X flow mufflers from Flowmaster and it will have a nice Rumble at idle and it was be a nice low throaty sound when you rev it and change out them cats for some Flowmaster cats I've got a 04 GMC Sierra with a 4.8 I changed out my factory cats and put into Flowmaster series cats that were $47 a piece I have true dual exhaust two and a half inch piping with two x flow 40 series mufflers and that thing sounds so good
The only way you’re getting rid of that clap is by adding mufflers or resonators lol
I almost didn’t recognize that it’s completely rusted out because of the clean exhaust 😅
Yikes... I wouldn't be bragging about that work.
I had a bmw m6 v10 and the exhaust i put on were true duals. It sounded okay but way too raspy. Installed an x pipe and she sounded amazing!! It did quiet down significantly with the x pipe.
It needs an equal-length crossover pipe to truly work well.
Using the x pipe or H pipe for sound alone is dumb. The connection between pipes is used to help equalize the pulses. Placement at different lengths help or hurt the process.
I would try a double H pipe, they tend to be a little deeper
I would have added resinator tips to get rid of that snapping/ rasp noise out
Still clappin
50 series Flowmaster makes the best sound
I think it’s still to loud needs a real muffler to bring the noise down.
X pipe should be as close to the motor as possible.
single 4 sure.
Sounds good. Adding some resonators would soften the clap more.
I can't notice a difference in the audio on this vid, it definitely needs a pair of resonators right behind the tips
"true" duals suck lol. its like hearing 2 4cylinders next to eachother
It definitely has a growl but it’s not for me . Cheers 🇨🇦
You guys should have used an factory style x pipe from the dodge charger and challenger, they scavenge better and the sound is better
That dodge Dakota needs to put a super 10 muffler on there.
need this exact exhuast recipe on my crown vic 🔥
He need mufflers like Corsa or Borla
Or carven🎉
It helped for sure
They both sound good
That thing needs a muffler so bad lol
Round 3 he'll have dynomax bullets between the xx
Double x pipe is defentily worth it 💯
It sounded good when you pulled away slowly
I'm really curious on what the chassis dyno would tell ?
When x pipes are made by Gillette, just keep stacking them up. If one is good two is better then three is just the beginning. Can we get some more X pipe
Double x pipe sounds a lot better more rumble less popping
It growls on the way up and down I like it my Silverado don't sound like that
To each their own. Personally, i feel xpipe into resonator,out to xpipe or just y from there would have cleaned up the sound a lot more. Regardless,nice truck👌🏻
With my Durango Tow n Go what would need to get that deep tone? Strsight pipe or? Wanting to get rid of mid muffler and resos
Nailed it with the double X..!!!😎
I mean a muffler would probably work
Now it could use a supercharger
I think That boy loud as hell either way! But that double X did clean it up nicely 👍🏽👍🏽. Good stuff
Thanks 👍
Sounds great..what did it sound like when it was too loud 😂
I love yallz channel man, you are the best exhaust salesmen out there!
Glad you enjoy it!
Those x pipes arent really effective at exhaust scavenging. The good ones are longer and actually create a vaccum in the exhaust. One way to test the x pipe is to blow compressed air in one inlet and hold something like a rag near the other inlet and see if there is vaccum
We will Never Allow AMERICA to Become Medical PERIOD,!!
40 series 2 chambers with one x pipe and you can't beat it
I can't tell much of a difference. Needs a flowmaster 40 series
This has me thinking.
I have a 1990 Corvette that i am doing a complete semi custom resto to.
I am at the point of saving for a massive motor machining and rebuild, nasty cam, heads, et'cetera. Currently, i have cat delete, x-pipe and 2 high end mufflers out back.
I am thinking of doing shorties, h-pipe, x-pipe and no mufflers out back. Should sound nasty! :) if it is to loud, i will be calling Karnage Performance. :)
90 Corvette- Do your manifold/headers as you wish into 2 pipes 2 1/4 or 2 1/2 dia depending on hp (2 1/2" supports up to 500ish hp) bring them back behind trans nice and even and side by side. Now bring these into a 4" dia pipe that you have flattened to 2 1/2" tall by about 5" wide and run this flattened tube down your driveline tunnel back to the rear transverse leaf spring splitting it again into two pipes to finish out your exit on either side at the rear as you wish, muffler or no muffler. I'd at least do a small resonator on either side if your Vette is cat-less. On that car forget the true duals unless you really want that raspy crap. The flattened 4" tube down the tunnel should come close in volume to 8 x one cylinders displacement which acts as a termination box and effectively shortens the length of the exhaust system that the engine exhaust flow "sees". This is going to increase your hp over a twin pipe system with a balance or X pipe and build a lot of torque and will sound rich and big block-ish. I don't suggest Flowmasters on this system. Something with a nice even non turbulent flow through.
Mufflerman 38 years, personally 60,000 muffler jobs and still counting.
@@JG-kv4oi , I like your thoughts on the design.
I will have to seriously consider that when i am to that point.
Put a flowmaster on one side and MWA on the other.
If you have a resonated x-pipe (x-pipe inside of a muffler basically) and a non resonated X-pipe back to back would that count as a double x? Or does the resonated x-pipe cancel that out?
Still a double X
@@tjtrainzCSX thanks! someone finally answered haha
@@PontiacFan4Life I just so happened to scroll through and noticed no one said anything lol
I think the X into H or H into X pipes are more interesting.
@@tjtrainzCSX i've thought about switching to X into H. I have double X currently but my low end torque kinda sucks and I hear H pipes help with that
Did he not think straight piping wasn't gonna be screaming
too stupidly loud.....put a couple 30" x 21/2" glaspaks on it and an x pipe just ahead of them......and I did performance exhaust before you kids were born
Damn. He should have gone with flowmaster flow fx rounds instead of double x's.
Straight Pipes all the way, although I like noise
