I have just fitted a HKS Super Power Flow induction kit to my 2002 Impreza WRX, it performs well apart from a very annoying rattling sound when you lift off the throttle.


EVERY BLOODY GEAR CHANGE!!!!!!

Any help and advice would be welcome

It has a Baily Dump valve fitted and this can hardly be heard now. Can the dump valve be adjusted? Is all this harming the Turbo in any way?
