I'm in the Seattle/Everett area and am looking to find someone with a K5+ GSXR-1000 with a M4 GP exhaust. I am interested in buying one, but would like to hear it before I take the plunge. Send me a message and we can meet up and go for a ride.

check out pnwriders.com lots of people in the seattle area on that site

Thanks, I'll check it out!
