Chrome. The Power Pro will outperform any exhaust system in its class. Take the proven 2-1 exhaust system, then add extensive Dyno testing and development. The outcome is that the Power Pro gives significant horsepower gain over stock and most other aftermarket exhaust systems. The overall performance gain gives great rideability with a deep and throaty sound. This exhaust is finished with a billet tip and equipped with 222° heat shields over its full length and a special collector heat shield that covers the 2-1 section. This means a brightly chrome exhaust without fear for blueing or other discolorations as found in un-shielded systems.
