Help -MY06 STi PPP engine noise
 

Guys, anyone had a noise develop on their MY06 STi PPP? On full boost i am getting a raspy noise from somewhere in the engine bay. Might be exhaust leak somewhere?
anything else it could be, turbo related?
Only getting it on high loading and boost. Car is running V-Power. No performance drop off. 6500 miles from new. About 1000 since PPP fitted.
Tightened up intercooler hoses and no change.

Getting ppp fitted did make my 03sti sound rather raspy. I like it though.

It might be that - not sure. Wasnt there originally, just developed.
