Brock's Performance Full System Alien Head 2 14" Muffler (BLACK) GSX-R 600 & 750 (2011-2019)

The Follow-Up To Our Best-Selling Exhaust System

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.
