Why do you require such a thing?

[theoblivious]

i dont have a turbo. therefore i lose back pressure

So........ Cat is still a waste of money.

I put a cat on my vw and wish i wouldnt have. 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!

Do you people not realize that the bulk of backpressure created is caused by your header? 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.

so my header is to big? i didnt think bout the header being the problem.

No your headers diameter shouldnt be too big! 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!

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