Never even though to look but couldn't find anything on mine either?!?! All I found was what looks like the yamaha
part number (EP5-something...). I do remember rangers always wanting too see the stamp in the past though. Hmmm, probably not a big deal, its not like you can't see the screen in the pipe. Can't imagine the ranger needing a coat hanger to see that!!! Anyway, mines a stocker still (sad face), they still stamp aftermarket stuff don't they?? I don't really care about the noise, I just want to smile when the cops are inspecting the bike, I just love that feeling...later, Gary
'99 WR400 with CA plates...ooooh yeah!!!
