Brocks Performance Alien Head 2 BLACK Full System for 2012-15 Kawasaki ZX14R w/ 14" Muffler, 397021. The Alien Head 2TM offers: more ground clearance, more room for the added fan, bigger flange kit and a deeper sound than the original Alien HeadTM 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 2TM exhaust system combines our legendary race-proven performance with the distinctive look and sound of the original Alien HeadTM 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 2TM full exhaust system to find the ideal balance of performance and attitude for the all new ZX-14R.
