WRX PPP folk who have added decat
Just wondering how this has changed your car, what decat do you have and who fitted it please? I have PPP at the moment and know that the kit comprises of the backbox obvioulsy and another pipe - I assume this is a downpipe which is different to a decat pipe? Sorry for the embarrasing lack of knowledge

I may be wrong but i think as part of the PPP, the downpipe should have been replaced with a sports cat, which is pretty much as good as a decat.
You will also have a cat in your up pipe, and a centre one also, after the centre cat pipe there is a pipe with a resonator in it (for noise reduction) then bolted on the end of that is your back box.

Thanks cook :=)
I wasn't sure what the second pipe was as part of the PPP...I like the sound of my car as it is but it would be nice to have it a bit louder...how can this be achieved without getting rid of my PPP bits then? Decat centre section?

get rid of the resonator box (pipe which connects to back box)
put something like an after burner centre section on that will make it a touch louder
ive just got that centre section and prodrive backbox and its loud enough to rattle the windows of the house

Not for the WRX PPP. The Mid-pipe is replaced with a straight through pipe but the original downpipe is retained.
Power Engineering told me that if you put a sports cat down pipe on, you should also replace the up-pipe and it can get too hot, break up and knacker the turbo.
