Supposedly most everyone that has compared the two like the PV1 better than the PV2 for some odd reason. I have no opinion on the matter your video sounds very similar to my PV1 except I would say the PV1 is a much lower rumble at idle and less raspy on the gas and a little tad less loud cruising, but it is hard to tell from the video. Sounds nice though I like the upgrade. I still can't decide if I want to keep the PV1 on or try something else. I really want someone in a VX to try this one:
