I has a stainless steal exhaust with a free flow cat, big difference. When the exhaust rusts out on my X I plan on getting headers, free flow cats and dual exhaust.
Originally posted by Samoanjoe: I hear a hi-flow cat can make a substantial difference in back pressure. Any mod you make to your exhaust system is ultimately limited by the cat.
Its pointless because I beleive there is 3 cats total on the x. 2 pre cats and an after cat.
