No, I never heard the PVs on the VX. I've heard them on another vehicle. We are lucky in that we have an excelent little exhaust shop down in Daytona. Marty turned me on to the ATs(even though he doesn't sell them). They shipped em, he did the stainless welding. I'm puting them on the '35 this weekend. They have an awsome howl when you wind it up. They're gonna rock on the V8. Wayne
