I got mine for $275 from Partshopper.com. Ive not had the chance to do a launch from a stop (damn rain ) but it sounds pretty good. 1st gear is kindof loud but once u get to about 50-55 it settles down, in 1st gear it sounds kindof motorboatish (sp) but cruising it sounds good
Ok I finally found a place to host the video of the before and after. The thing that sucks is that they kind of dumped the quality so I'm not sure how helpful it will be. Well if anyone wants me to send them the file or if someone has a server I can host it at PM me and we'll work it out.
Special bonus* I put a small clip of my fastback on the end for eveyones viewing pleasure!
