I have an 07 WR450 that the dealer uncorked for me. The pea shooter is out of the stock silencer. I'm starting to ride more aggressevely. Also been reading comments in magizines about noisey dirtbikes not doing us dirtriders any good. Since I didn't take it out, I was wondering if it was possible to put the pea shooter back in? Is there a quiet aftermarket can? Bike runs perfect as is. I have the blue screw. Will I have to rejet?
