Pro Circuit – R-304 Shorty Silencer (KTM)

When every twist of the throttle matters, the Pro Circuit R-304 Shorty Silencer is what racers reach for. Designed purely for competition, this compact silencer gives your KTM sharper throttle response, harder midrange punch, and that crisp two-stroke bark that just sounds fast. It’s lightweight, race-tuned, and built to squeeze every ounce of performance out of your setup.

The R-304 uses a brushed 6061 T6 aluminum body paired with a 304 stainless steel intake tube and end cap, giving you a silencer that’s both strong and feather-light. Inside, E-Glass packing keeps it performing at peak levels longer, and when it’s time for a refresh, the allen-head screws make repacking quick and easy. Every unit is TIG and MIG welded by hand in the USA, built to handle real race abuse while maintaining that factory-level precision.

Why We Like It:
It’s all about that sharp, instant response. The R-304 makes your KTM feel more alive — faster to rev, quicker to recover, and more explosive when you crack the throttle. It’s lightweight, durable, and gives your bike that unmistakable pro-level sound.

Why It’ll Work for You:
This silencer helps your engine breathe and rev faster, which means stronger power where you can actually use it — right off idle and through the midrange. It’s simple to maintain, built tough to survive hard motos, and keeps your bike feeling crisp and responsive ride after ride.
