FMF Powercore 2.1 Shorty Exhaust Muffler (025317)

FMF created the Powercore 2.1 Shorty Silencer, which utilizes a shorter aluminum canister and inner core. This design decreases the amount of back pressure in the muffler, which on a 2-stroke will increase throttle response and low to mid-range power. If you spend most of your time riding on tight tracks and trails, the Powercore 2.1 Shorty is the silencer for you.

• Better throttle response throughout entire RPM range
• Smooth power delivery
• Unique canister shape based off of 4.1 four stroke technology
• Easy repacking
• Can be used with stock or FMF pipe
