I tell ya what man i bought a doma pipe and silencer, its out of Belgium and i tell ya what i have a screamin machine, i dont know if yours does this or not stck but i can pull up a fifth gear wheelie with no help from the clutch, so if you ask me get a doma and obtw doma i guess teamed up with KTM to find out what the best designs would be for peak performance. It is listed under ktm hard parts. good luck man but i would have to say DOMA
