sorry stupid question but i was wondering if there are two different pipes? for CA emmisions and just Fed??? and is there a difference??????
thanks

 

need help fast.....

 

Yes there is a difference, and why you pressed to need help so fast?

Cali spec is on cars that are 2k1 and some 2k that have 4-O2 plugs infront of the engine.

You need to make sure you get the right pipe otherwise you just wasted your cash.

but i have a 03
i think its all the same right???

 

You need a CALI spec Y. Anything above 2k1 is all Cali Spec.

thanks for the info so there only one out there for the 03. i was also wondering how you would know its a aftermarket y pipe. im buying one from a friend of a friend and i dont really trust him. is there like some kind of mark??? or lable?

 

You won't know until you install it. The dealer will know because it won't have Nissan's part number on it. I'd make sure it fits before you hand over the money.

 

is there a big difference between the stock y pipe and the warpseeed pipe???

thanks

 

Yes.

1) The pipe is physically bigger in diameter:
Stock is 2".
WSP Y is either 2.25" or 2.5".

2) The stock pipe has a "U" shaped bend on the rear pipe. The WSP Y does not.
