This Muffler is designed to increase the horsepower and torque throughout the entire power curve and give you a noticeable power increase that is very usable and beneficial, no matter your riding style or ability.
Features include space age internal packing for maximum packing life and a high-flow modular end cap. Internal core shape uses high-flow technology. Enhanced sonic evacuation provides for higher flow and increased power.
Muffler includes removable spark arrestor. 97.5dbA sound level.
This accessory is restricted to closed-course use.
Fits:
The patented Resonance Chamber Technology enhances and refines exhaust pressure. Its patented core shape lowers sound level while maintaining maximum power output, and the patented canister shape increases internal volume for more sound-absorbing material. Factory Forward Engineering centralizes mass and is less prone to impact damage.
Maintenance is easy remove four screws on the front end cap, and the innovative rear end cap simplifies the installation of the spark arrestor (sold separately) or tuning tip inserts. Includes QuietCore 94 dBA insert. Meets most sound requirements.
It is compatible with stock or GYTR header and made in the U.S.A.
This accessory is restricted to closed-course use.

Fits:
GYTR Clutch Components are precision machined from aerospace-quality aluminium alloys with a unique hard coating. This provides superior performance and clutch feel, as well as excellent component durability. The patent-pending auto oiling system forces oil through specially cut holes in the pressure plate, into the inner hub and then to the clutch plates. This results in improved clutch performance, with lower clutch temperatures, less clutch expansion and extended clutch life.
