Under bonnet noise 3000RPM?
 

Hi all

Just thought i'd ask on here before getting the car up on the ramp!

2005 Newage STI - Turbo back Miltek system

When driving under load, just before 3000RPM im getting what sounds maybe like a slight exhaust blow noise, but seems to be coming from the engine bay?

Its hard to tell where, as I only hear it when driving, it doesnt seem to make the noise any further up the rev range. I also done seem to be down on power?

I was thinking possibly a leak from the up-pipe/gaskets, but wondered if anyone had experienced the same or anything I should be looking at first?

Thanks

Up pipe Alex is my bet mate

Yeah what i'm thinking Rob, will put it on the ramp tomorrow and see if I can see any signs of leaking
