Pro Circuit – R-304 Shorty Silencer

When you’re chasing every fraction of a second, the Pro Circuit R-304 Shorty Silencer delivers the edge you need. Designed purely for closed-course racing, this compact silencer gives your two-stroke lightning-fast throttle response, a sharper power hit, and that crisp factory tone every racer wants to hear. Lightweight, tough, and built for speed — it’s a race weapon through and through.

Constructed from 6061 T6 brushed aluminum with a 304 stainless steel intake tube and stainless steel end cap, the R-304 is engineered to handle the abuse of real competition without adding weight. The E-Glass internal packing lasts longer and keeps performance consistent, while allen-head screws make repacking quick and hassle-free. Every silencer is TIG and MIG welded by hand in the USA, ensuring strength, precision, and a perfect fit. A double-walled mounting bracket keeps it rock solid, and the short-can design gives you that instant, snappy throttle feel that wins races.

Why It’ll Work for You:
