my HKS BOV is pretty loud. the oompa loompa cop in davis (you know who he is... short, shaved head, mustache, YOUNG, pissed out at the world). He said he pulled me over for accelerating too hard, etc. in downtown davis. NO ticket, just all attitude until he saw my drivers license and realized i was probably older than him. The car is getting more popular and recognized to be fast. A loud exhaust, and louder BOV just draws more attention to you. But, who doesn't like their BOV???
