I bought this pipe to plop on my Gyro, but that's going so this must go, too. It came off a DBM 50cc dirtbike, which as far as I can tell is a KTM or LEM clone. No dents, some surface rust. The exhaust and removable silencer were made by Giannelli, and looks to be made well. You can check them out here: http://www.giannelli.com/eng/home/
Plop it on, hack it up, mod it. $25 plus shipping.
