Our Best-Selling Exhaust System
The Alien Head™ Exhaust System combines our legendary race-proven performance with the distinctive look and sound of our Alien Head™ muffler and 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™ Full Exhaust System to find the ideal balance of performance and attitude.
