ShortMeg 2™ Full Exhaust System
The ShortMeg 2™ offers a full through 2.25” diameter secondary section for increased exhaust flow and builds upon the legendary, race-proven performance of the original ShortMeg™, while adding a distinctive look and deeper exhaust tone. This system is a must for the sportbike owner who is never quite satisfied with factory power.
Manufactured to stringent specifications, Brock personally designed and hand-tuned the ShortMeg 2™ full exhaust system to find the ideal balance of performance and attitude from the stock to the highly modified sportbike. The ShortMeg 2™ exhaust system stands as the benchmark of cutting edge power, design, and style.
