Well, i'm installing my headers and i was looking to replace my catalytic conv. Now, in va, they don't test emissions and such so i was wondering how much different, in power terms, is a test pipe and a high flow cat? which would you guys recommend? Yes, it's illegal, but it is a valid question no flaming please
