Extra time on research and development ensures your exhaust has the ultimate in quality workmanship, ease of installation, and the best performance possible for your motorcycle.

Whether hitting the track or sharing a ride with someone, this system has you covered.
The M4 Standard / Race Series Slip-On Exhaust has a built-in baffle, tuning the exhaust note for a crisp head turning sound.
Unique silencer packing gun insures even distribution of packing material.
M4 has built a quality fitting exhaust that is a breeze to install; all mounting hardware and instructions included.
The Shorty slip-on exhaust system will shed some weight over stock to give your sport bike improved power-to-weight ratio.
Bolt-on and slip-ons systems utilize the stock header assembly, but remove the stock canister's restrictions, for better sound and an increase in power.
Up to 7 horsepower gain.
Note: All M4 systems are designed and intended for closed-course competition use only.
