The torque baffle should be the one shipped with the pipe. It is closed on one end with holes on the sides and of course open on the other end. The competition baffle is a little longer and open straight through with what looks like a "torque cone" welded on one end and larger holes on the sides. Competition baffle is much louder with little backpressure. My dyno tuner swears that even on my 120 Merch the Torque baffle will still provide better streetable power. Once the engine has some miles I'm going to try both baffles to see with my own eyes.
