The Pro Circuit 304 Silencer, manufacturer part number SY03250-SE and vendor part number 792-5206, is designed for select Yamaha YZ250 and YZ250X two-stroke applications. Its extended silencer body is recommended for most two-stroke engines and helps provide reduced noise output compared with the shorter Pro Circuit R-304 model. This replacement silencer is engineered to work with compatible Yamaha exhaust systems and is an excellent choice for riders seeking dependable performance and durable construction.
The silencer features a brushed aluminum body with a stainless steel inlet tube and stainless steel end cap. This material combination supports long-term durability while giving the exhaust system a clean, high-quality appearance. The Pro Circuit 304 Silencer is intended for use with a Pro Circuit pipe unless otherwise specified by the application. Review the applicable exhaust configuration before installation, as certain fitments may require use with the stock pipe.
Fitment includes 2003 through 2010 Yamaha YZ250 models and the 2016 and 2017 Yamaha YZ250X. Designed specifically for these Yamaha two-stroke motorcycles, the Pro Circuit 304 Silencer provides application-specific compatibility when paired with the correct pipe and mounting hardware. Always verify the motorcycle year, model, pipe configuration, and installation requirements before ordering.
