They have zero low end torque anyways. Just put a test pipe in.

Why do you think your having back pressure problems anyway? Back pressure only makes your car run smoother at idle and low rpms, but at WOT it dont do shit!

The small diameter tubing of a 4-2-1 or a 4-1 header creates the most of the pressure, a cat/testpipe will not cause any noticible pressure loss. The removal of all of the exhaust will however.

Its a 2.5" high flow but i still regret it. I bet you that running a test pipe on your car will actually increase your hp #'s, by a slim margin, back pressure is over rated! 😄

Why do you require such a thing?
