The Follow-Up To Our Best-Selling Exhaust System
The Alien Head 2™ offers: more ground clearance, more room for the added fan, bigger flange kit and a deeper sound than the original Alien Head™ for the Gen 1 ZX-14's. We also moved the power curve up, since the ZX-14R has a stroker engine and doesn't need additional low end power.
The Alien Head 2™ exhaust system combines our legendary race-proven performance with the distinctive look and sound of 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 all new ZX-14R.
The Alien Head 2™ exhaust system stands as the benchmark of cutting edge power, design, and style.
