so justin...you only have one cat on your car right now? is that legal? noones answering my other thread, and im getting the car in 2 days...i need to know :-X i was thinking about getting all cooleeze stuff (downpipe, and the cat back on suprasport) plus a high flow cat to put in the cat back. one high flow cat, im assuming thats legal in NY state...someone at advanced auto parts said it would be.
if the car is n/a...then id lean towards the smaller of the two mufflers, just because of torque in the lower bands being present with that kind of muffler. i dont think it would be a whole lot though...so its up to you.
