As of right now you need 350z TP's, Cats, or HDC's. but IMO id only want headers if I could run TP's. the purpose is to get the most free flowing exhaust setup on that end of the car. This really is small beans. And to everyone complaining about the install time. That's old news. Been that way since the 350. Time to learn how to work on your car.
