B-Pipe and Emmissions
#4
Ok then, thanks for the responses. For some reason though I thought I remembered a thread in the past that said you would not be able to pass emmissions, but oh well. Thanks.. What are the gains for the b-pipe though, any good?

Minimal, probably not worth the price but if you have the money than do it ... Emmisions are afected by catalytic converters and there are none present in your car in the b-pipe, only in the header(Cali spec)y-pipe and right before the b-pipe, but not in the actuall b-pipe.

Any type of cat or pre cat will help in passing emmissions, and the less you have, the less chance you have of passing.. And when you eliminate all of them which include the y-pipe and the "test pipe" a test pipe is a catless replacement for the stock unit, you will be phukked when it comes to emmissions. If you get a y-pipe, warm up your car to test emmissions. The reason nissna leaves the pre-cats close to the engine is so that tehy can warm up faster ... in other words you NEED a cat to pass emissions and a y-pipe and test pipe wont work ... Do what you want I tried .. I rest my case.

your catalytic converter is the one you need to pass emissions, you can have a straight pipe after the cat and still pass emissions. (with a muffler). y-pipe is ok, too. if your not too sure, go to your auto part store and find this thing where you can lower your emissions. i dont know what its called but i happend to see it, thought you can use on an old car.

But would this make it so I can't pass emission? http://www.customenterprise.com/view.../vts/design017

I am also looking into getting a b-pipe (well for about 3 years now looking) but not sure if I should go resonated or not. I have the stillen rear section with stillen y-pipe and just curious on how it will sound not resonated.
