If you’ve got a DR-Z400SM, you’ve got options when it comes to exhausts. The RS-2 single-sided system is a great all-around pipe that’s lightweight, has good ground clearance, and gives you big power gains. And it looks cool. If that’s not enough, it comes with the little touches and features you’ve come to expect from Yoshimura. It has a plasma-cut heat shield with our Yoshimura logo, high-quality chrome steel exhaust springs, and even spring vibration dampers with the Yoshimura logo molded in. Want to spice it up a bit?
