Ok, I just got a sound clip from SPAZZ (thanks, man). Here it is:

VX w/ PV2 Muffler

Mine has the exact same tone as that, but is a bit louder, since I have no tail pipe or tip.

Anyhow, I think it sounds awful. It's embarassing to drive around with it. I have a friend picking up a Flowmaster 50 for me for this afternoon. I'm gonna put it on right after work.

Again, if anyone wants to buy this thing, with a 2" inlet conversion to fit stock pipes and custom dual 2.5" outlets for a dual exhaust. I've got about $140 of materials and 3 hours of work into it. I'll sell it for $50 plus shipping costs.
