BPM Twister MKIII Turbo Back for MY02 WRX, used. The exhaust has the usual scrapes, etc. on the underside- as in NOT PRISTINE, but functionally perfect. Killer sound and performance, just be prepared never again to have a stealth-quiet car. Locals only- Bay Area. PM me if you're interested

Here's the specs- http://www.bpmsports.com/products/twister.htm
