what does x pipe do i want to run true dauls on my truck and i hear some of you guys are useing x pipe

 

It equals out the exhaust flow between the two pipes, giving a little more power, especially down low. It will also make the exhaust quieter, due to less turbulence.

 

I think X-Pipes on trucks are a joke.
I definitely believe it benefits the cars, but not the trucks.

I am not "in the know", but take it for what its worth.
I am trying to be as least technical as possible.
My understanding was that the effect of an X-Pipe is that it kind of acts like a tuned header, in that it does kinda equal out the exhaust flow, and kinda creates an alternating vacuum on each exhaust tube as the exhaust pumps out.

Tuned Headers mean that all the pipes are equal length from the exhaust manifold to the collector (which is why they are so twisty).

An X-Pipe works in a car because their exhaust runs the same equal length all the way back to the tail of the car without any major unequal bends (both sides of the exhaust pipes are the same all the way back....mainly in length), so inserting an X-Pipe will, in fact be an advantage, because it will synch the headers together.

HOWEVER, on a truck, the exhaust pipes are not equal lengths all the way back.
The drivers side pipe is much longer, seeing that it makes a turn to the passenger side of the truck to join with the other exhaust pipe before the transmission crossmember. If you put in an X-Pipe on a truck, and for it to truly work, it would have to be installed directly to the headers....just about anywhere after that, the 2 exhaust pipe lenghths are not even.

I hope that made sense to people other than myself!

 

but most people using an x-pipe usually dump the exhaust right after the muffler. so the pipes never reach out from behind the bumper. you are correct in the pipe turning to the passenger side. but that imo isn't that much more pipe to make a huge diff.

 

2 feet of extra pipe on the drivers side makes it totally different lengths. Unequal is unequal. I think it does make a huge difference, but that is only my opinion.
The F-Bod guys are perfectly equal all the way to the X-Pipe, fortunately for them. I'm not reputable, I don't imagine, but call someone who is, like MTI, or other specialty exhaust fabricators (KOOKS). I'd imagine they'd tell you the same I am talking about.....maybe?

You think I would buy a long tube header with one of the pipes 10" longer than another??....no way! Because, in order for them to make the good power, they need to be tuned (all the same length).

 

What does that have to do with anything?

Whats behind the X-Pipe can be any length its the X-Pipe forward that counts.

 

What difference does it really make? Most of the tests I have seen between Y, H, and X the diff. were so minimal that IMO it didn't matter. 5rwhp to me is not worth changing anything that can cost over $100.

Personally I like the sound better on an X-pipe because it is smoother and quieter. I swapped the H on my Mustang to an X and on my Vette I run an X AND an H and it is very quiet for not having any cats, makes good power too .

 

Both cars you mentioned are CARS! Kinda part of my point.
MTI strongly recommends X-Pipes on all their Vettes & Camaros, especially in combo with LT headers.

Also, I completely agree its not worth the money for the performance to be had, but if I had a Vette, and I was doing the exhaust anyways, I'd say why not.

With the 6.0 swap we just finished and the addition of the TOGS, we went ahead and did my exhaust over anyways, but no X-pipe, because IMO, it will only restrict and hinder the flow of the unequal pipes, IMO.

 

I did a quick search and found someone supporting what I'm trying to say:

Read BenKey's post about 3 or 4 down on this thread.

I hope this turns into a debate, because if an X-Pipe really does help, I'll throw one in this weekend for the heck of it.
I saw both sides of the argument on that thread as well.

 

i missread what you were saying about the length in pipe when i typed that. thinking you were saying it was unequal cause if you use two exit pipes one goes relatively straight and the other curves towards the driver side. i went in and edited it when i realized you were talking about coming from the header to the muff.
