Hey guys I was on the magnaflow site the other day looking for some high-flow cats to put on my car. I couldn't find anything that would bolt right up to my car. I wanna run either mac midlenths or some shorties through high-flow cats, custom Y-pipe, and into my magnaflow cat-back exhaust. So I need help in determining which size high-flow cat to go with. Is there anybody here running a similiar setup? Oh yeah I have a 2002 Z28. Thanks all answers appreciated.
