I bought my 1150gs with a y piece & standard can fitted & to be honest was a bit disapointed with the performance. So after reading some posts on the forum about fitting a stubby i bit the bullet & bought a 2nd hand cat converter & a piece of scrap exhaust pipe from a local exhaust manufacturer. I fitted the cat & made myself a stubby from the scrap pipe,took about an hour all in. & Fcuk me what a difference!! It now pulls like a train & runs a hell of alot better. If your swithering over whether to do this mod yourself just do it.
