On my 97 DX Coupe, I want to replace the header with a more free flowing one, but the problem is that the catalyst is on the header, so if I buy an aftermarket one it won't pass smog because I live in south cali. Could I buy the aftermarket header, then get custom downpiping with a high-flow cat somewhere in there and still pass smog?
