I'm using it on a WR250F '09. The exhaust pipe contains FMF's TitaniumMega bomb. The sound is rough from the time of Idling, and it is powerful without complaint when driving. I've used it both off and on and it sounds great in both directions. Of course I felt the power was up. It feels like it's pulling me along from the start of opening it up. Once you experience it, you won't be able to stop.View Detail
