Yoshimura is one of the biggest names when it comes to performance exhaust systems for your 4 stroke motocross or enduro machine. Offering a range of full systems as well as slip-on mufflers for most modern bikes from Yamaha, Honda, KTM, Suzuki, Kawasaki and Husqvarna. The range of Yoshimura RS-4 exhaust systems features a blend of stainless steel, aluminium, titanium and carbon fiber construction materials, allowing options that better serve the rider when it comes to their primary focus, price or weight. The typical RS-4 full exhaust system features stainless steel header and tail pipe, aluminium muffler and a trick carbon fiber end cap to complete the look. The RS-4 Signature Series makes use of more titanium to bring the weight down even further. If your budget isn't up for the punishment of a full system, Yoshimura offers RS-4 mufflers as a slip-on exhaust option. 

When it comes to off road riding, there are substantial performance gains that can be achieved with an aftermarket exhaust. The ability to better tailor the top end power of your KX450F, or add more bottom to your CRF250R are all too common items on a rider's wishlists. With easy fitment, Yoshimura allows the option of a full system exhaust or allows you to stick with your stock header pipe and add on a silencer, both great options to get a bit more power to the ground on the supercross track.
