other than passing emissions tests and price, what are the differences? power, sound, quality? im pretty stuck on a prochamber, and am going to order a new midpipe tomorrow, what do u all think?
i love loud exhausts but im no fan of swapping pipes back and forth. i would go the route of a catted midpipe. i had a high flow cat setup before and it made my spintechs sound pretty good but not loud like they are supposed to be. my offroad H pipe brought out the beast in my 89 GT. if u have flowmaster or mac cat back, it should sound nice with a catted midpipe.
