I'm confused with all the exhaust options out there. I wanted LT headers but we have E-check. Is there a LT setup that I could run and still pass?, If not and I went with shorties, What would be the best , a catted H or X pipe and which cat or axle back? I've heard some say shorties aren't worth it and others say the jba shorties worked pretty well. In your opinion, what would be the best legal exhaust combo for my car? It's mostly a street car and want to go with a procharger sometime. My hp goals are around 450 at the wheels with a procharger, what exhaust do I need to get there and still be legal? "thanks"
