    Hi all,

    Could someone tell me what the difference is between the 2006 WR125 restricted exhaust (8000A5584) and the Full Power (8000A2773) one?

    What type of restriction do they have? I'm looking into restricting my bike back to street legal power. I have the throttle limiting spacer and the correct jetting etc for it but only have a FMF Fatty exhaust system.. So I figured that maybe I could find a stock one and restrict it? Or restrict the FMF one?

    I dont know about the older ones but my '13 has a spare road version with a catalyitic converter in it near the inlet. Slightly less smooth and curvacious.. Not sure why you would want to do that .

    As far as I am aware one part number for reduced power is WR exhaust the other is CR exhaust, the shape and size is smaller on the reduced power exhaust and I think the silencer for a WR is slightly longer and for US that have extension on the end cap
