Alright, help a brotha out. Getting ready to take my headers off. I bought a Y-pipe a few weeks ago. It came off a 4wd and being mine is a 2wd.... Can anybody tell me if there is in fact a difference between a 2wd and 4wd Y pipe before I go yanking **** off my truck? I can't see there being a difference. But I am probably wrong.

 

depending on the years i think you will be fine.
fyi i put the stock y pipe from my 2wd rcsb onto my ccsb z71. the only difference was the shape of the cats.

 

Its from an 02. Im seriously thinking about trying this when my manifolds get in. Just wonder if it will actually fit.

 

Anybody else before I give this a go??

 

as long as its a 4.8 or 5.3 it should be fine. the 6.0 y-pipes are different.

 

You shouldn't have any problems.

 

Well it fit and fit good!! Sounds a hell of alot different now...
