I know I should just donate, but I will give this a shot.

What are some different y-pipes that will fit a 2000 gxe maxima?
What is the best-bang-for the buck y-pipe?
Is there a siginificant difference in HP gains between different manufacturers?

I believe I have a fed spec since I live in Missouri
This is a direct bolt on correct?

I've heard of Cattman, Warpspeed, and Stillen are pretty good. Also have heard of such brands as Topspeed which I can find for $140 shipped, and Budget.

 

your shot isnt working...donate!!!

but since im bored.....
all y-pipe do the same thing and provide the same performance gains.

now donate to get the rest of the answers

 

Maybe you can sell me your OEM one?

 

if they all do the same, how do they produce more horsepower then stock? Possibly by eliminating the pre-cats?

 

The pipes diameter is larger allowing more air to flow. Interested in selling OEM?

 

I might sell the oem y-pipe, but not sure yet. Will this alter my emissions tests, produce a check engine light, or have any negative effects on my car?

 

You no there is more then one page on this forum if you like down on the bottom right hand corner of the front page you see this litte number thingy well that for more pages why not just look a couple back and read. Dont be lazy. If you want reall increase get hotshot headers.

 

i'll be getting a y-pipe soon and wont have any use for my OEM one. But its got 140k miles and its been through 5 NY winters. I'm not too sure on its condition, if that matters. Not trying to thread jack.
