I went with Borla Exhaust with Kooks 1 7/8 with a 3" out and kooks catted midpipes. I would go with uncatted if you don't have to do smog tests or anything like that. Corsa is also a really good brand for Exhaust, just remember you get what you pay for so if it's expensive there is more than likely a reason behind it. Check out Marylandspeed.com for parts. If your trying to go crazy loud SLP loudmouth is stupid loud. I hate it but to each there own right. Hope this helps some.
