I've had my MRT H-pipe and catback system with a flowmaster catback for a while now, but now I have enough money to buy a nice set of headers. The only question that rises when looking at headers for me is that on every application I've looked, Kooks, SLP, and Hooker, they all seem to have an X pipe that is either required or optional. My question is , is it impossible to get a set of headers to connect to my MRT H pipe?
