I was at Starbucks once and went to start up my VX to leave just as a cop pulled in. He walked over and took a walk around my VX, and asked if the exhaust was stock. I told him it was called PowerVault, specifically designed for the VX. I expected some little lecture and maybe even an inspection ticket at that point. But, all he could say was that it sounded great for a 3.5 V6 and he thought it sounded similar to his V8 5.0 Stang he had at home.
Also the same cop who told me at a later date (ya, I see him at Starbucks all the time now) that the VX reminds him of a 427 Cobra modified to be a 4wd vehicle, heh.
Still loving my PV!
