The Pro Circuit 304 Silencer, model 304 and manufacturer part number SY93080-SE, is designed for most two-stroke applications and is a recommended performance replacement for compatible Yamaha YZ85 models. Its slightly longer silencer body helps reduce exhaust noise compared with the Pro Circuit R-304 model while maintaining the performance-focused design expected from Pro Circuit exhaust components.
Built with a brushed aluminum body, stainless steel inlet tube, and stainless steel end cap, the 304 Silencer combines durable construction with a clean, high-quality appearance. The materials are selected to withstand the demands of off-road riding while providing reliable service and consistent exhaust performance. This silencer is engineered to fit 2002 through 2011 Yamaha YZ85 motorcycles, making it a practical choice for restoration, replacement, or performance exhaust maintenance.
Fitment: Fits 2002-2011 Yamaha YZ85 models. The Pro Circuit 304 Silencer must be used with the appropriate pipe configuration: use with a Pro Circuit Pipe where specified, or with the stock pipe where required. Verify the existing exhaust system and application details before installation to ensure proper compatibility. Vendor part number: SY93080-SE.
