TRUE dual exhaust is what old muscle cars & trucks had: Two individual pipes that don't converge at all: No Y-pipe, no H-pipe ("balance pipe" is what we called them years ago), no X-pipe, no muffler with two inlets and only one outlet, etc. They may not have had the best exhaust flow, but it's what gave them their unique sound. When you factor-in no cats, and common mods like headers and glasspack mufflers, you end-up with that classic muscle car sound.
On the contrary, the H pipe is better for vehicles that do towing due to the added low end torque, the X pipe is good for the higher rpm torque and horsepower. The H pipe is a better route if you're going for a tow rig or a town cruiser
Wrong. H pipes balance pulses. Xpipe does the exact same thing plus induces scavenging from the shape. This creates power increase everywhere over an H. Most noticable in the low to mid range.
@@garlandjones7709 please supply documented data for that claim, when common knowledge is that an X-pipe benefits the top end & an H-pipe benefits the midrange, even the fella in the video says as such re: the X-pipe.
@@phil955i common knowledge where? A Walmart parking lot? Ill send you a better message when i get off work. While were waiting, why dont you tell me why a straight pipe with 90 degree flow rotation in and out would make more power at any rpm than say a 60 degree or smaller transition in flow? Fyi, exhaust is air too.... this shouldnt be bard to ponder on.
@@garlandjones7709 what's a Walmart? I'm from the UK. And the gobbledegook above makes absolutely no sense. I'm waiting for your documented facts with bated breath.
Thought about doing this on my truck. I had tried 3 diferent mufflers and had nothing I liked. Finally installed an 18-inch magnaflow last week and absolutely love it. It has added a lot healthier tone and rumble plus some power. It's crazy I took off at every red light last week and managed to average 15.5... before I averaged 14.5 driving it normal. That muffler helped me out a lot. I can't wait to see what it does when I can keep my foot out of it. Plus I towed my bass boat Monday and it helped a whole lot with getting up to speed vs the other mufflers I've had.
Another benefit with the x pipe (not sure if anybody commented) is exhuast scavenging. It helps prevent to much back pressure from going back into the engine
@@Jack-bj4jw xpipes scavenge. Nothing to do w backpressure though. You're right in that sense. Backpressure "talk" is usually legit circumstances with backpressure being the wrong culprit. You can still go to large on exhaust. This is where that myth argument comes into play and that comment is usually used by those that dont know what they're talking about.
@@stew-03 yes and no. I view it backwards from what you're thinking but the result is the same. That view looks at a stock running vehicle. Mine would look at a bare engine perspective with no pipes at all as a starting point. You search for ways to keep exhaust velocity high without hindering flow to raise torque. It's not that the other drops it. Its dropped from the start if you're viewing the engine by itself. If you're looking at it from the the engine now with a set of headers and you're adding pipe from the collector to tailpipe tip, then yes a loss of velocity and scavenging will reduce torque. This is a byproduct of the pipe that is unavoidable. The key from a designer's perspective at this point is to design those pipes from start to finish where the least amount of loss is prevalent. This is where the X comes in along with a handful of other things that aid in reducing this loss. And it's not so much that an X is gaining power at this point as it is that its reducing loss from what youd have with open headers. Now this same concept would not apply to cast manifolds in the same sense as they're not designed for optimum velocity already, they come engineered from the oem with the whole system meeting whatever criteria the manufacturer had set. The function of the Xpipe though will not change though. It still does th e same work no matter what is put behind it or in front of it that may hamper it. Edit: there is not one single app an xpipe will not improve unless the design of the x itsself is bad or hampers flow. Location is important too and this ties into velocity. Many are setup poorly as they are set too far back from the collectors of the headers. When you think of a v8, dont think of an 8 cylinder engine. Think of 8 one cylinder engines. The idea is to have each one in equal harmony. Same concept behind why you want equal length primaries on your headers. In many instances you cant make them equal whether its exhaust, fuel distribution through carb. Head flow per port bc of valve train components or oil or water passages, etc. Some cylinders run hotter than others needing more fuel. Some get 20-30cfm airflow less on 2 cylinders than the other 6 bc of intake design. You want to find a way to equalize these as close as possible. Again, this is the function behind the X. It's not just a theorized flop like a "tornado" or throttle body spacer. It is a legitimate working product. How much it helps isnt set in stone. It's only relative to how much its improving on what your starting point it. And that goes for every other product on every other application. Every V engine made except for v12s benefit from these for those reasons and because of natural imbalances due to firing order. Inline engines benefit from this too. It's the same concept behind tri-y headers, just further down the line.
Hell yea brother do it for dale!! Love the shirt. I got duals on my truck an I’m pissed I don’t have true duals on my 5.3. One in 2 out I’m looking to get the x pipe
I have a true dual on my 1996 Chevy sliverado and I put free flow cats and a 6 inch glass packs in both sides and then a 3.5 inch tip with a 45 degree cut. I absolutetly love this setup and plus it’s loud as hell, but bc it is a glass pack it takes a couple for the sound to really break in
I remember my father's boss had a 350SS short short bed the man he purchased this truck from had took the factory catalytic converter and positioned it in between both pipes an H pipe but he didn't do it for performance down here early 90s we didn't do smog test the cat just had to be there and technically it was!
I have a 1998 Chevy Silverado with high flow cats and I have put an x pipe and with out and I like it the best with out the x pipe it runs the best on my truck
I watched your first video a few months back on the exhaust and I went and had it done the exact same even same dump angle! Love it but not to loud for true duals! Awesome truck man!
It has already been mentioned in the comments that an X pipe will rob your engine of low end torque, also the X or for a pickup truck a H pipe should be mounted as close to the engine as posible for best scavenging and flow, horsepower only varies about 2-3 hp between X,H or straight pipe setups .
Actually! Engine masters did this test and a 3" y pipe with single 3" out the back through a straight through magnaflow made 25 more hp thank x and h pipe and master torque down low.... the numbers don't lie and the old wives tails people claim without proof is hilarious. Especially the old exhaust shops...
Dude the X pipe should go the CLOSEST to the headers. If you can get it right after long tubes or headers to mids that’s where. The X scavenges less and less the further downstream you put it.
What is best for raising low end torque? I dont really do racing and I dont hot rod around. My foot is just a little bit heavier than average. And I do ALOT of towing. 90 percent of the time I at least have a empty trailer.
I've been shopping for an obs chevy truck for the last few weeks and it has been difficult to find the right one. I was hit by another driver last year and the pos totaled my beloved 98 obs k1500 stepside chevy silverado. An x pipe was gonna be my next mod before the crash. RIP Bella😔 A feller miss's his truck
Hey I have a built motor with a str stage 2 cam how do you think a x pipe with true duals sound i don’t want really any clapping a little bit is ok though keep up the great work on the videos👍👍
I have 3" true dual exhaust no cats double H pipe and single chamber thrush bottles full 3" manifolds back on my 98 Z71 5.7 I will never do anything exhaust less then 3" ever again. 3" full duals sound so much better way deeper I prefer the H pipe over the x myself
Hey man awesome truck and video my 02 Silverado with a 6.0 long tube headers with cats true dual exhaust no mufflers sounds awesome in your opinion will my truck sound better with a x pipe....with my 4.10 gears and 4 speed I think my top end is good
Did you get exhaust drone after you installed the xpipe? I had true duals then put in the xpipe which helped in gas mileage and power but it created a drone because of the exhaust balance.
Let me know if thats a good price i just got it like 45 minutes ago & it drives so smooth the 1st agreement was for 1700 with the 4-2 Kevlar Powerband Corvette servo, performance torque converter & stage 2 shift kit but when he open it it had other thing burned 300 more but oem specs parts but adding the extra performance parts 3200 tax included & the truck runs like when I got it in 2009 let me kniw if thats a good price thanks
When you get on it and let off and you have that crackle does that just happen when you let off the throttle it drive or do you have it in over drive or what because i love that crackle
Hey what's up buddy great video and explain on that xpipe. So I have done a dual exhaust on my 2018 titan and I put blackwidow mufflers on it . So if I go and get this xpipe put on it will sound even louder and add a little bit of power to my truck? Thanks bro
I have a 2008 Chevrolet Avalanche 5.3l i recently did the following to my transmisdion they charge me 3200 00 idk if thats a good price I copy & paste the text from the transmission shop: Per our conversation we will be rebuilding your transmission super duty. Which inclu 2/4kevlar band, Corvette servo,performance torque converter, stage 2 shift kit, sumshell ( the beast) , 10 clutch pack raybestos performance, 5 gear rear planet assembly , 10 vane kit pump gears synthetic fluid 1 year warranty plus 2 fluid or complete transmission service
Try a cammed 4.8 with longtubes 3 inch y pipe to 3 inch single exit ... sounds good but cammed ya know lol but truck is stupid loud really wanna change to x pipe butttt i like my set up
@@oscarlongoria1817 headers, larger collector to y portion of piping y pipe to 3 foot straight pipe with turndown for velocity. About to do x pipe or di,do muffler may try both . Self tuned 5.3 headers 4.56, 35's 4wd e fans 160 therm mags delete with isolated ait running ethanol and eating newer 5.3s that are on stock tires
I have a 2002 GMC Sierra 8.1L extended cab 6in lift. was wondering if I should do long pipe headers or shorties. Or keep it stock?? I wanna run axel dump xpipe
