Pro Circuit - 2-Stroke R304 Shorty Silencer (Honda)

Pro Circuit – R-304 Shorty Silencer

The Pro Circuit R-304 Shorty Silencer is built for riders who want maximum throttle response and race-level power delivery. Designed purely for closed-course performance, this compact silencer sharpens your two-stroke’s hit off the bottom and through the midrange, giving you that crisp, instant snap every racer chases. It’s light, tough, and ready to perform when the gate drops.

Constructed from 6061 T6 brushed aluminum with a 304 stainless steel intake tube and stainless end cap, the R-304 is made to take race-day abuse while staying light and responsive. The E-Glass internal packing delivers consistent performance and lasts longer between repacks, and allen-head screws make maintenance quick and easy. Every silencer is TIG and MIG welded by hand in the USA, ensuring precise fitment and long-term durability. The short-can design and double-walled bracket complete the race-spec package, giving your bike that unmistakable factory feel and sound.

Why We Like It:
It gives your bike that sharp, immediate power you feel right off the throttle. The R-304 makes the motor come alive — fast revving, strong mid hit, and that crisp Pro Circuit tone that sounds as good as it feels.

Why It’ll Work for You:
This silencer helps your engine rev faster and pull harder where it counts most — from corner exits to jumps. The shorter design sharpens throttle response without adding weight, and the brushed aluminum body keeps it light, strong, and easy to maintain. It’s simple to bolt on and instantly makes your bike feel race-ready.
