The 304 Silencer is recommended for most two-stroke applications. The slightly longer body offers additional top-end performance while reducing noise output. The brushed aluminum body and stainless steel inlet tube and end-cap gives you a silencer that looks as good as it performs.
The R-304 silencer was developed as a full-race two-stroke silencer. The compact design of the short aluminum canister offers optimum performance gains and is recommended for closed-course racing only. Hex head screws are used to secure the inlet cap and can be removed easily for quick re-packing of the silencer.
