I got mine from a local dealer just outside of Philly. I know I've seen them on eBay and they might have been selling the front bumper seperately..not sure though.
I like it alot. It has a more exotic sound than something like flowmasters. I also have an off-road H, so I dunno how it would sound with a catted H or X.
I've gotten quite a few compliments on sound. It sounds good rather than just loud.
