i have search the forum endlessly and not found a clear answer...

can someone please check out the picture of the y-pipe towards the bottom of the post above and tell me if it is cali or fed spec? and if it would work on a '99 or just 95-98. the seller is not sure, but i would really like to know...

thanks to all who have helped with my exhaust questions and in advance to those who are willing to!

and this is the best picture of it as of today.

 

that is a fed spec ypipe

 

okay, i'm half way there.

'95-'98 or '99? or does that even matter?

 

99's have a pre-cat in the header. That ypipe will not fit on your car unless you convert to a fed spec front header.

 

/\ not all 99s have the pre-cat, I know mine doesn't.

 

oh, well I take that back then. Look at your front header and see if there is a big cat attached to it. The flange will look a lot different than the flange on that ypipe.
