S&S Cycle #550-0004B - Power Tune® Dual Headers - Chrome

The S&S Power Tune Dual header system is not just an end to the headache of the constantly failing stock "Y pipe" header design. With an improved pipe bend profile, the exhaust heat is moved farther away from the rider and passenger. A hidden crossover chamber provides classic true dual styling, but provides the improved midrange torque and horsepower of a 2-1 system.
