DescriptionYoshimura has been the official exhaust supplier to Team Honda Red Bull Racing for several years now. All of that experience has helped Yoshimura in making an exhaust that compliments an already great bike.
Aside from our complete systems for the CRF450R, we are also offering a Header Kit which mates to the stock muffler. This Header Kit features a titanium tapered header pipe designed for optimal flow and performance. Get all the benefits of titanium while retaining your stock muffler.
The Header Kit will also work with the RS-4 Slip-On, should you decide you want the Full System in the future.
Note: This is for the Header Kit ONLY and does NOT include a muffler.
