Catted Up Pipe on Bugeyes?
 

Ok guys I can't recall and I am trying to help a mate out. Did the 2002 ADM WRX have the cat up pipe issue or was that only the 2001 model?

models without AVCS ie 01 & 02 WRX (not sti)

Yeah only 01 & 02 wrx's. The usual problem is that the cat breaks up or melts sending bits into the turbo wheel and bending blades.

Sorry to high jack this thread but what is a catted up pipe, from the work its self sounds like there is a cat in the up pipe?, but wouldnt this re strict the flow a little bit ?

Thats exactly right. There is a cat on the up-pipe. Yes it is a restriction, but more so, as the cat ages, it will eventually break apart sending pieces of the ceramic core flying directly into the turbo exhaust wheel. Usually resulting in damage to the turbo.

Ok that leads me to my next question how do i get rid of it and how much will it cost ?

replace it with a cat-less up-pipe. Either aftermarket of from a different model WRX like the 03+ WRX or 02+ STI.

Will it fit on a GC8 also where can i buy onme are there web sites around that sell them and is it an easy diy job, whats involved ?

Your GC8 doesnt have a cat in the up-pipe. No need to replace it.

Hmmm ok then all good i guess, did all gc8 have no cat in the up pipe?
