Both were impressive! I liked the sound of the white Lexus, though, better than the green one. I agree that it reminded me of a 392's exhaust note. Would love to see if dual x-pipes hurt performance numbers.
Very very well done video. Exactly as described, straight to the point, no extra music drowing out the exhaust, cold start, rev, underload, high rev, video of completed exhaust, everything you need to make a good decision for your car!
Wonder what the exit speed (CFM) between the two be for the scavenging. Is it compounded like a compound turbos, or does it just smooth out the tone and make it deeper
@@NXT_LVL Corsa was the first to use the double x-pipe in their catback systems. There might be a flow advantage to it. One thing I do know, it does sound good.
First off the single xpipe car needs to fix that ground with the radio... geeze. Second, the double xpipe sounded deeper and more throaty, when it launched it just sounded much cleaner
I’d maybe add something on the rear like a vibrant or something along those lines to remove the residual rasp, but the dual x-pipe is my favorite by far.
An x pipe equalizes the exhaust pressure from bank to bank. It is pointless to have a second one. It would be like adding a y pipe from the manifolds, then dualing it out with a second y pipe. Then adding an x pipe afterwards. No ryhme or reason, no benefit. Unless you want a second one just to say you've got 2 x-pipes.
@@drbumripper x-pipes do reduce the sound output. The tone is changed by diameter. I'm running single 4" tailpipe and it is very deep for the neutered 190hp 350 v8 that I'm running it on. I have a 24" 3"id glasspack and a 30" 4"id glasspack as mufflers. It's mellow, but deep. 2½" downpipes from long tubes then a 3" y pipe into the first glasspack. Then an adapter to open it up to 4" and the 2nd glasspack. 45⁰ tailpipe out the rear passenger corner. I just think that 2 x-pipes is redundant. If you want it quieter, add a resonator. I guarantee you can find a resonator for cheaper than an x pipe. Same with drone.. do some math, add a j-pipe. A second x doesn't fix anything that the first didn't already do.
@@EricErnst X pipes have been proven to help higher end power of the curve. Like a Dual vs single plane intake. All depends on how you want the curve to swing. More low end, run the H... high end X... want it to sound like an old cigarette boat (2 4 cylinders arguing if you have a weak cam), run it straight out. The double X is a newer mindset via Borla/Corsa again, sold for the Coyotes in design for that 7-8,000rpm peak hp point. If you want sound run it open, if youre wanting to use scavenging to get you those few extra power numbers in that old 350, run a crossover or Y but don't run too large of a diameter, or you'll stall the speed of the exhaust pulse and cause a turbulence leading to lose down low.. or everywhere in a small displacement 200hp setup. I'm running the stock 2.5' single setup in my truck, basically a 289; making about 240hp.. if I went duals i'd have to drop the diameter to keep the velocity up (thumb over a garden hose)
@@NXT_LVL Dual x pipes promote scavenging more than a big single exhaust with an efficient Y? Forcing the exhaust into intersecting zigzag shapes instead of straight doesn't seem efficient to me. But what do I know?
@@EricErnst Depends on the size. There should be some enigne masters episodes on YT you can watch based on exhasut or even the flow testing that people do on their own in their personal shops. Or the full technical scientific showing the low vs high pressure affect. Now does a double compound the scavenging, that I'm not sure of. Though I have yet to see any dyno or anything to say whether or not it increases flow dynamics or the velocity or even the effectiveness of scavenging using the double X. It's like anything else performance wise. do your homework and try to verify the claims. People still buy into spending $500+ for those cold air intake kits that truly do nothing but pull hot engine bay heat.
@@drspeed2006 right, I know that. But that has nothing to do with the needle on a cars fuel gauge indicating a nearly empty fuel tank which is what OP was referencing.
no wonder my car actually sounds better. I had my welder tell me he'd be installing an extra x pipe I was hesitant about it along with my already huge borla xs muffler, but in reality made it wake the exhaust tone up and even sound like a gtr slightly. This isn't a vq video but no-one else talked about this elsewhere.
H pipes suck ass on literally every application. theres not a single instance where H is better than X unless you simply dont have the space underneath to put an x pipe without having it hang low.
I've got a 1996 2nd gen LT1 5.7/350 with a single x-pipe with dual Flowmaster 40 series mufflers. I love the sound, but there's a bit of droning at certain rpms. I'm wondering if a second x-pipe would help with that. I've got a spare x-pipe and a set of straight through resonators. I'm just trying to figure out exactly what I want to do. There's not a lot of space to work with. But after watching this, I think I might have to do some experiments. I should probably get some quick connect band clamps before I start. That's more cutting and welding than I want to do. After I have it figured out, then I can weld it solid
Mine is same except full exhaust including hurricane headers, twin 2.5, twin x, more space between mine, no cats only a pair of straight Tru mufflers at the end Edit: maybe I'm biased, but I still think mine sound the best, as impossible of a job as it is, you need the headers
I got a big question for yall exhaust system experts if I do a double x pipe on a 3.6l pentastar would it damage the engine in any way? Or is it something not recommended for that engine?
Coming very soon to this town… Two dead vehicle’s at the side of the road because their owner’s spent money on want’s, not need’s. And in other news, Tow trucker operators are having a wonderful year!
Going back to single x pipe after a year .... With my new Borla mufflers the dual X's are too restrictive to that awesome Borla tone. And every exhaust is different ... For instance mine sounds quite different than this as it's hurricane long tubes (which of course = no cats), cutouts, dual x pipes, mufflers, tips. And cheap mufflers DO sound like shit
There is a guy with a Ser Sentra that kinda sorta shown how it could sound. He ran headers that separated the exhaust into 2 banks. His videos sometimes show up when you search these.
That's gonna make it run like shit 👍adding x,h pipe is like increasing your exhast pipe's diameter for exhaust scavenging. Plus It only works if it's at the correct length from engine.
@@lewokejamesyep, it's called a ground loop. Sometimes it's caused by a blown Pico fuse in the head unit & can be fixed easily by wrapping a copper wire with no insulation around all of the rca outputs & securing the wire to the casing of the radio at ont of the Phillips screws.
Hey I got a question. You guys should make a video or videos. Of strange or un usually exhaust vids. Like if someone does a Van, or small trucks. V6 cars that are not sporty.
Y’all are confusing the difference in sound from the tips, not the single or duel xpipe. The white car is deeper because it has massive 4inch tips. While the green one has a small factory tip.
Dual x pipe 👑

Dual x wins the game...
I have a goal jus to meet u guys someday, yall good people who jus enjoy wut they do, I wish everyone was like yall, straight awesome peeps
Ok I’m getting a second on x pipe 😀 it give it like a more deep sound , no raspy love it
The throttle response looks better with double xpipe
Oh that dual X pipe is meannnnnnnn
dual x is more refined and deeper tone too
Dual x pipe has much deeper tone than the single x pipe
I’d maybe add something on the rear like a vibrant or something along those lines to remove the residual rasp, but the dual x-pipe is my favorite by far.
I wonder what difference it would make if the dual high flow cats were removed. And it was just the dual x pipes instead
"High flow cat" for legal reasons
The dual X gets my vote.
Lexus SC400s are one of the best cars of the 1990s.
Stop telling people! They're already getting pricey!😂
Out of curiosity which was louder or seemed louder at idle the single X pipe or double X pipe
White car sounds like a factory 392 charger / Challenger
That first lexus owner needs to get some them lights turned off before wasting money on the exhaust lol
Wht one sounds like a coyote
The dual x pipe has a under water sound i don't like .
Been wanting to hear a challenger 392 with double x-pipe
Me too or a rt

So i need to dual X my Fx35, got it
It almost seems that the dual X-pipe is quieter than the single X-pipe.
They sound similar. But the duel has better idle and revs. So I'm going iwht the duel X pipe on this one.
*Dual
Dual x pipe makes it deep sounding
Now show H pipe for a real comparison...
H pipes suck ass on literally every application. theres not a single instance where H is better than X unless you simply dont have the space underneath to put an x pipe without having it hang low.
i’m running 3 x pipes on mine and you really do notice the difference the more x pipes you add!
🤣🤣🤣
I'm running 10 x pipes
My car is made out of x-pips and a jazz my pants everytime I ... it.
My names Xavier i changed all the plumbing in my house to xpipes and I left my wife so we could be double x's.
Is there difference in power the more you add the x pipes?

Changing to a non chambered muffler will help with that drone and add a resonator

Not a fair comparison the white car has high flow cats. Otherwise good job
there might b something wrong w that green 1...
