Pro Circuit R-304 Silencer

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. For maximum performance, the silencer does not include a USFS spark arrestor.
