The Kerker Megaphone Series has a racing pedigree few can match! Recent dyno tests proved you can gain up to 9% more horsepower over stock systems. Dynoman recommends re-jetting your fuel system to match aftermarket exhaust systems! We offer many other models of Kerker and Supertrapp headers - please contact us if you don't see your bike listed!
