Why is he clueless? You can run a decat 2nd cat pipe on an impreza, while keeping the cat in the downpipe, or having a sport cat downpipe in place.
The second cat can be removed for road use also if a sportcat downpipe or original downpipe cat is used, as the prodrive ppp pack cars have this without being illegal or failing mot’s.
Thanks

Best to visit an exhaust centre and let them take a look at it, also the induction kit won’t help on the noise front.

A decat pipe and a sports cat …. WOW – how did you manage to fit them together ?!

Does this mean that the end of your tail pipe sticks out further than it should

Numpty!

Im pretty sure what robin meant was having bought both but not on at the same time e.g sports cat for mot purposes and decat for the rest of the year or for the race track.

i have a decat pipe, also with a sports cat on my janspeed twin exit exhuast.. so i got best of both worlds and power because my decat is racing rep adding 12 bhp (dyno tested) with the sports jansped cat also adding more power ( Dyno tested again)

so if you can afford both its so worth it
