Question MY03 de-cat Down Pipe

Thinking of fitting a de-cat pipe on my MY03 WRX PPP.
Ive taken out all the other cats.
(not too worried about emissions )

Anyone know how easy it is & any suggestions which one to go for ?

Thanks!

a mate has just put a decat downpipe on his MY03 WRX and he's over the moon with it, the turbo spools up quicker and he was told it give around 10BHP, he hasn't had any problems with low speed driving, idling, etc, he's convinced me to get one now!!

Has your mate got the PPP pack on his car?

think places like TSL will always say you need a remap, but lots have done it with out

never read about any one with problems at low speeds, I assume as this will be closed loop a remap wouldn't change this problem but makes me think its not common as we all would have it

the problem will be with overboost, if you have a boost gauge you could keep an eye on it - I went for a re map as I have enough problems with out creating more
