YOSHIMURA RS-12 SS/ALUMINIUM FULL SYSTEM This exhaust fits: YAMAHA YZ250F - 2024-26 Kit Includes: RS12 Stainless/Aluminium Silencer with Carbon Fibre End Cap Stainless Steel Header While other exhaust brands just carried over their Yamaha YZ250F offerings to include 2024 model, on the dyno and track, the new YZ told us there was more on the table. So our R&D team went to work to optimize the new Yamaha. The adjustments to our spec proved what the 2024 YZ was telling our team was right. Our revised RS-12 Signature Series full system added 2.5% max HP and 2.8% max torque over stock. This is why we develop and test all of our product! Our RS-12 mufflers have loads of features including our PTF insert system that makes changing inserts a breeze and an optimized muffler shape with added volume and brake caliper clearance.
