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.

even when you take the cat off if you add a y-pipe, you will still pass the emissions if your car is warmed up for a bit b4 the test.

NmexMAX

iTrader: (22)

No it won't ...

MaximaHunty

iTrader: (4)

See what I mean, this stuff is kinda confusing.. Haha

NmexMAX

iTrader: (22)

Well you have people that aren't too informed, and they skew good information, Who are you going to believe .. me or him ...

MaximaHunty

iTrader: (4)

I don't know who to believe because I don't know hardly anything about this subject. haha that is why I started this thread...

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.

When you say cat, I think you mean pre-cat... not the main cat ... if you take off the main cat along with any pre-cats, you will fail for sure...

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.

Puppetmaster

A "straight pipe after the cat" would be a b-pipe... just to clarify, because most people know a straight pipe or test pipe as the pipe that replaces the main cat...

Teufelhunden

iTrader: (8)

yeah i meant b-pipe, but usually when you buy a b-pipe, theres like a little bulge (or something) on it that i guess restrics the flow? i was talking about just ==== staright without restriction part, like a custom made b-pipe.

MaximaHunty

iTrader: (4)

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

Puppetmaster

iTrader: (48)

That is not a b-pipe... that is a straight pipe that replaces your main cat. So yes, you probably would fail emissions with that on. Btw, I really doubt that it'll give ya 8-11 whp by itself.

MaximaHunty

iTrader: (4)

I know it is not a B-Pipe, but I was also looking at that..

Puppetmaster

iTrader: (48)

Sorry, it was just in the way ya phrased the question... it was like it continued form the initial question. ANyways... yeah... unless your cat is shot, and ya have other mods, it might not be worth it getting a straight pipe... if ya had headers or a y-pipe, along with a cat-back, it might give ya a little bit, if not, then its not really worth it, IMO, since the stock cat flows just fine.

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.

MaximaHunty

iTrader: (4)

Ye sorry, I asked it weird. But thanks for the info.

Puppetmaster

iTrader: (48)

Interesting... I've heard the Stillen with a resonated b-pipe, I think I'd leave a resonator in for that... I'm actually thinking of un-resonating my Frankencar b-pipe as well... but have yet to do it... I kinda like the way it sounds now, not too loud and the tone is nice.
