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.

    Easy Install

    Posted by Garth on Jan 30th 2018

    Hi there, my name is Shawn (aka Garth285) and I just wanted to write you guys to thank you for such a great product! I recently installed your Alien Head 2 full system on my Uncle Bill's 2012 ZX14r and it was one of the easiest installs I have done in the 10+ years of working on bikes! Everything fit together so nicely and was very well put together, ZERO clearance issues and zero fitment issues! The bike went from making 185hp to 200hp with just the pipe install and a ECU flash from Guhl motors and now that it is dialed in on the street she really makes some monstrous power! Anyways I just wanted to say thank you guys for making a great product that I would recommend to anyone who is looking for a rock solid exhaust!
