The Alien Head 2™ offers: A full through 2.25” diameter secondary section and bigger flange kit to take full advantage of state-of-the-art high performance aftermarket cylinder head porting techniques. These free-flow exhaust enhancements allow the performance curve to be moved up, via aftermarket ECU modifications when using a stock displacement engine, while also allowing larger displacement engines to breath freely – a must for the loyal Busa owner who’s serious about competing against today’s alternate brands of modern sportbike.
The Alien Head 2™ exhaust system combines our legendary, race-proven performance with the distinctive look and deeper tone than the original Alien Head™ muffler, which has become a favorite with custom builders to showcase more of today’s big tire/custom swingarms. 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 Busa.
The Alien Head 2™ exhaust system stands as the benchmark of cutting edge power, design, and style.
