The new Alien Head™Exhaust System combines our legendary Generation 3 Front Section (full) with our new Alien Head™Muffler! The result is race proven performance with a one of a kind drag race look…. without the inherent drawbacks of a sidewinder. There is no reduced right hand cornering clearance or rear brake lever to pipe clearance issues. NO fairing modifications are required and the stock oil cooler and lines remain intact.
