Am I missing something then? Where is the second CAT? What is the point in buying an aftermarket Up-pipe which all the tuners sell etc. Some claim to have sports CATs ie 100 cell and others completely de-catted? Example - http://cgi.ebay.co.uk/Subaru-Impreza...d#ht_573wt_941

Well it does say 01-06 WRX as well so that would be true for it to be a decat with what JGM said.
Good to know for sure my GB270 wont have an up-pipe CAT.
On the subject of CAT's which CAT would you recommend replacing with a sports CAT if you want to retain the ability to pass an emissions test (assuming the other will be decatted) or does it not really matter?
Would a single 100 cell sports CAT in the system be boarding on passing/failing the emissions test? (ie you'd have a decat in place of the main(?) CAT)
Am i right in saying you can get a longer downpipe which has the a sports CAT built in and the main CAT removed ie 2nd CAT straight through?
Would removing any of the CAT's require a remap even if you have PPP?
Does the centre section silencer make a massive difference to how noisy your system is?
(from my point of view i'm talking from a Hawkeye 2.5 WRX with PPP)
Sorry for all the questions, i'll get my own thread if its seen as hijacking!

100cel sports cat is border line from the cars I have seen.. get the cat nice and hot and it usually passes, yes they do the longer downpipe with 2nd cat decat..
the centre section does make a reasonable difference to noise yes.
it would need a remap is you changed cats yes.. maybe okay if you retained the catted downpipe standard.

Up-pipe = Manifold to Turbo
Down-pipe = Turbo to centre section
As Simon says, you may be confusing which is which mate, you will have a cat in your down-pipe but not in the up-pipe.

JGM cheers.
So i'd be ok on the standard PPP map with a 2nd decat, centre section and backbox but still having the standard downpipe with its standard intergrated CAT?
tbh i wouldnt want it loud (just a bit more vocal than the stock PPP setup) so sounds like a silencer in the centre section would be the way to go.
