The CS is actually more than a cat-back. It also replaces the midpipe so I guess you could call it J-pipe back. I got rid of the OBX header and put on the stock exhaust manifold.
Besides the cat-less CS exhaust, is there a really good catted exhaust that y'all can think of that would fit my MP3 with a nice sound..though I am thinking of just getting the CS
If you're staying catted, mine will sound great on your car. I'm thinking of trying the CS exhaust with my header set-up. Buy yourself a muffler and tip from magnaflow and have a local exhaust shop install for you. Total for everything (parts/labor) should be 350ish.
