Dual Exhaust help???...

[super-gt]

Alright guys, as some of you may know, I'm swapping an LS1 into my GT this summer. I would like to do a dual side pipe set up. I was thinking I would just build pipes off the headers than add small mufflers and high flow cats on each(emissions...) then dump them before the rear wheels. What I'm wondering though is that I know alot of people do an H-pipe or X-pipe before going to seperate exhaust pipes and dumping. My question is would I be better off going with an X-pipe or something and than seperate pipes or can I just not use anH or X-pipe? Does using an X-pipe help the exhaust ''scavenging'' more than not using one???Basically would I benifit from one...

Thnx again,
-Taylor

x pis or cross over pipes just balance the exhaust from side to side ive seen some guys have results and others say that dont notice anything one thig though if you want it to be rightput a fuel cell it the box cause theres no nice way to run exhaust around the gas tank

Yea I am planning on a fuel cell and new fuel pump.
I'm just not sure on the exhaust cause I have heard people having issues when they don't run an H-pipe or X-pipe...they said they were losing some mid-low torque.

If you want to keep the bed of the truck clean, Look at getting a gas tank that fits where the spare tire is. This is the setup I was thinking of for 88 S-10 I have. A gas tank from a G body van with FI will fit in the spare tire location. That will give me the range I want being it's a 34 gal tank and will free up both sides of the frame rail for the dual exhaust with a X-pipe. In all cases I have seen, the X-pipe has added power, sometimes as much as 30 hp and 50+ lb torque. Stay away from the H-pipe as the X-pipe will do better all the time.

I have seen 3-10 hp gains on X pipe vs H-Pipe (usually 3-5).
