What is the point of the dual BOVs Ken? One to recirculate the air and the other for the sound? Venting to the atmosphere doesn't make the AFM very happy on my turbo truck. The BOV on my car is quiet (stock 1G DSM) but come on Ken you don't need the sound for people to know that it is fast. <img src="/forums/images/graemlins/evil.gif" alt="" />
