I bought a 98WR400 second hand from a guy that had a muffler shop mess with the baffles so that it let loose some extra muscle...and noise. The bike is too loud for long rides and I want to add a Baja kit so I can ride it to the trailhead (much too loud for street riding)! I am sure one of you wrench/performance heads out there has put on an aftermarket muffler and has a stock muffler kicking around collecting dust. Sell it to me and I will collect some dust on it using the thing. Drop me a line. Trent.
