got a 3 inch mac catback for my solid swap. fits like total dog shit. i got the left muffler and tailpipe to fit good. but the right side i can get it to do shit. i thought i had it in a ok place but it rattled like hell and banging off the breather on the rear end. any body got any advice?? another question, the pipes the go from the mid pipe to the muffler, does it matter witch side they are on?
