Hey there, I'm new to this Saab Forum..

This question is for a buddy of mine who has a 2006 9-3 Aero. It has the 6 cylinder Turbo engine and is quite quick.

I'd like to chip in with him on a new Blow Off Valve for an x-mas present and was wondering what the best BOV would be for his make/model/engine. He basically want's to hear that Turbo loud and clear (and wants to let the GT Mustang drivers he frequently dusts to know as well..)

We've both done full suspension work on our cars, but haven't touched the engines yet. I figure the BOV is a good place to start.

Any recommendations on a brand/type that is LOUD and high-quality would be most appreciated! Thanks!
