Which X-pipe?
 

I just ordered the SLP exhaust system for my 03GT. I haven't installed it yet..but i hear that it's the loudest exhaust around. SWEEEET!!!! Anyway...i'm also thinking about getting a SLP x-pipe later on. But i don't know which is better. Since i don't have any other major mods to my car would it be wise to go with a catted or o/r x? also headers will eventually come, but is it true that SLP x-pipes only work with SLP headers? Just wondering! thanks

hey i got the slp cat back on my car and the sound is sweet... i' mgoing to get the catted...because a stock gt engine needs the back pressure...the o/r x u might lose hp... now as the mods keep coming you can always remove the cats and install a straight pipe to make it an o/r pipe
