Supertrapps area cool design. I don't think that the supertrapp is designed with a 2-stroke in mind. More of a 4-stroke thing where you can add/remove discs to tune the back pressure. I had one on my 1978 Can-Am 250 stock from the factory. Seemed ok but it was a devil bike that I had to sell quick to preserve my health so I didn't get to spend a full season with it. Cam.
