The Pro Circuit 304 Silencer, manufacturer part number 1052585, is designed for most two-stroke applications and provides a balanced combination of noise reduction, durability, and performance. Its slightly longer body produces reduced sound output compared with the Pro Circuit R-304 model, making it a practical choice for riders seeking a quieter exhaust configuration without sacrificing the performance benefits of a quality aftermarket silencer.
Constructed with a brushed aluminum body, stainless steel inlet tube, and stainless steel end cap, the Pro Circuit 304 offers dependable service and a clean, durable finish. The components are selected to withstand the demands of off-road riding while maintaining a professional appearance. This silencer is intended for use with a Pro Circuit pipe as specified by the manufacturer and should be installed according to the applicable exhaust system requirements.
Fitment includes 2025 Husqvarna TC 85 models in 17/14 and 19/16 configurations, the 2025 KTM 85 SX 17/14, and 2025 GasGas MC 85 models in 17/14 and 19/16 configurations. Verify the motorcycle model, wheel configuration, and existing pipe setup before installation.
