i am looking for a blow off valve that will be really loud and is good for the t2. I was planning on boosting no more then 10psi. I am wondering if i will need a atmosphere bov to make a loud sound?

 

I also need a BOV, except it will need to be good for up to 18 poungs of boost.

I can tell you that venting to the outside of the car is going to make it sound a LOT louder (if that is what you want).

What BOV is everyone else running? and Where did you buy yours from?
