Description
The Alien Head 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 Alien Head, while adding a distinctive look and deeper exhaust tone. This system is a must for the sportbike owner who’s never quite satisfied with factory power.
Manufactured to stringent specifications, Brock personally designed and hand-tuned the Alien Head 2 full exhaust system to find the ideal balance of performance and attitude for the stock to highly modified sportbike. The Alien Head 2 exhaust system stands as the benchmark of cutting edge power, design, and style.
