The Alien Head 2™ Exhaust System combines our legendary race-proven performance with the distinctive look and sound of our Alien Head 2™ Muffler. Our most popular exhaust system, Brock personally designed and hand-tuned the Alien Head 2™ Full Exhaust System to find the ideal balance of performance and attitude. Keeping our creative Z125 Pro owners in mind, this low-mount exhaust option was designed to tuck up tight along the engine to provide the most ground clearance available. Now you can stretch and lower your Z125 Pro without being restricted by your exhaust.
