The Follow-Up To Our Best-Selling Exhaust System

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.

    Haven’t installed it yet but I’ve had it on previous busa and zx14. Best sounding exhaust in my opinion. Fit and finish and longevity is top notch. Shipping is fast placed order on Sunday had it by Wednesday.
