Dudes, anyone got a yz or some other aftermarket silencer that would fit my wr400 to part?
I bought the FMF Ti4 silencer and midpipe for my WR400 and it made a world of difference - gobs of power and now it seems to have the power of the YZ's. Just remember to jet up about 2 sizes on the main and pilot jet after the pipe - you'll need a lot more feul after your engine gets new lungs!
