exhaust X Pipe

[kglowacky]

Been wondering how important an X-pipe set up is on a LS swap. I have a LS1 swap out of a 02 Trans am and am running dual exhaust with no x pipe. Seems to run fine. What are the advantages or disadvantages of installing an X-pipe or is there any.

I wouldn't use the word important, its about sound and fitment. the X pipe sounds different than H pipe and the true dual with no connection between each bank has a different sound aswell. Best bet youtube sound clips, but X pipes sounds more cleaner to me, H pipe has more popping tones to it, true dual pass..

if you are have the capability of welding it in yourself, buy both options and try it out.

not really going after any sound. I like the way it sounds right now. I was just wondering if these higher hp motors need the x pipe to balance the pressures. I want to make sure I am not damaging my motor long term.
