The new RS-3 mini muffler is an instant classic. Yoshimura hasn't built this beauty in a few years and is no longer included in any current exhaust system so they decided to make this mini gem available for their Builders Series. Expensive - yes, but you would have the sickest system at the show with this bad boy. Sound, looks, and performance! Grab one before they go extinct again. Stainless steel or carbon fiber construction, a hard anodized end cap, a rolled and welded titanium tip topped off with Yoshimura R&D racing badging. Now you can purchase this builders kit and customize your build with a RS-3 mini classic. Mounting hardware, including a muffler clamp and insulator, is included. Weight just 2.5 pounds. Proudly designed and made in the U.S.A!
