Been runnin bmp pipe on 13 900xp since March. Little louder than I anticipated- I like it but wife not so much. Installed with QSC clutch kit at same time. I should have done pipe alone fist cause the clutch is awesome, so not sure about pipe.
Pipe started getting louder this fall, so called bikeman. Sent it back and they said it was coming apart inside and was none repairable. They replaced with a new chrome pipe (had black) with no questions asked.
Recently did elm reflash with RVS performance-pretty awesome results without tapping into guts of motor.
