I just got my Warpspeed Y-Pipe today for the 01 Max. It came with the CA emissions installation instructions, but I do not have a CA emissions car.

Has anyone else purchased one of these for an 01 Max, and received these instructions. I called Warpspeed, and at first the girl said "Ohh Noo", then she said that "she thinks it's probably the same". But I don't know if I trust that, since I do live on the east coast of Canada, and the shipping cost of an exchange would be pretty high (Especially with customs) - I paid an extra $51 COD because of it.

If anyone can clarify, it would help my conscience a bit. If not I guess that I'll go ahead with the install.........Once I get to a transmission shop and flip the bill of a possible re-build ........

I am not sure the differences in the two pipes. Hopefully these pics help. Check this thread.

I think it's the same-- I don't have the `00-`01 FSM here to check.

Unscrew O2 sensors.Remove stock y-pipe.Ensure all gaskets are removed. (round crush gaskets in front, copper gasket to cat)

Ensure o2 sensor bungs on new y-pipe have antiseize installed (they should already, all the WSP's used to, at least years ago).Ensure new crush gaskets are installed. (I generally reuse the gasket to the cat, since the stock Nissan one is a nice copper piece).Reinstall y-pipe.Reinstall o2 sensors.

You'll probably have an easier time if you remove the heatshield on the cat (four 10mm bolts) to access the y-pipe-to-cat nuts, and the stock y-pipe probably has 2 bolts holding it on in the middle, too-- your aftermarket y-pipe is lighter and won't need those/won't even have a mount for those.

beancooker's link looks right, your Fed-spec car might just be short an o2 sensor or two.

After doing a dozen or so of these I think I have the installation time down to about 45 minutes or an hour, and that's mostly just because I'm cursing at dropping the socket and elbow joint I need to tighten the bolts on the y-pipe! :p

Thanks for the extra instructions.

I was trying to find out if the pipe itself was the same. I posted some pics of the pipe on the other Y-pipe thread that you replied to today. I posted it there so that you guys could get an indication of their work.

It does look similar to the pipe on Beancookers thread there. I guess that he has a Fed emissions Max. Well at least now there's some pics of a new WSP Pipe on the forum.
