So being as I have the ss/sc, I was wondering about exhausts. I have found a site to order a cat back with mandrel bends (minus the muffler to allow you to do your own muffler) I was just pondering if I should go 3 in or 2.5? Does it make that much of a difference? Thanks ahead.

 

2.5 if your not planning on making around 300whp, 3 if your gonna go with that serious of power.

 

yea.. id just go with 2.5 if anything ur losin power with the 3in.. except of u have around 300whp
