Hi guys - recently returned to the Impreza fold after a break of five years. I've bought a nice Hawk Spec C, which was imported into the UK in November Engine wise, the car is pretty much standard apart from an HKS exhaust and intake.

Had a full service and remap for UK fuel, and it made a healthy 349bhp on RCM's rollers, which I'm pretty pleased with. However, I'd like to maximise the potential of the OEM turbo, so was thinking of a freer flowing downpipe fitted with a really decent high flow sports cat. Then replacing the second cat with a decat pipe to further improve flow - all followed by a map tweak of course. I don't want to replace the exhaust as it's performing well enough and it sounds perfect to my ears - lovely and quiet while cruising with a nice bark when giving it the beans.

My question is this: will the car still pass emissions with this configuration? Also, can anyone recommend a really good sports catted twinscroll downpipe? (I see RCM do one).

Many thanks in anticipation
Andy
