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 Hayabusa owner who’s serious about competing against today’s alternate brands of modern sportbikes.

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 Hayabusa.

The Alien Head 2™ exhaust system stands as the benchmark of cutting edge power, design, and style.

    Alien Head II

    Posted by Rasstuss on Apr 19th 2024

    I love the exhaust note & look on the 25th Anniversary Busa. Weight savings is a plus. However, the install was a major pain in the arse. It is easier if you remove the radiator. There is no room to work in there. The gaskets did not want to fit. They were larger in diameter than the copper crush gaskets that were original. The exhaust flanges were bending at 10 ft. lbs. of torque so thats where it ended up at. It didn't leak, that I could hear anyways, so I will have to keep an ear out just in case the bolts start to back out.

    It can super fast. I installed it myself and it wasn’t super hard just a little common sense. Instructions are not broken down for each step because it can go on multiple bikes. But I’m super excited and satisfied with system.
