Samson Exhaust introduces the new Powerflow III series of exhausts, which are the most powerful two into one exhausts made for all 2010-2012 Harley-Davidson dressers and Road Kings, the company says. The power is generated through a series of chambers, which Samson refers to as the "Power Chamber," which helps condense and intensify exhaust flow, resulting in extremely high horsepower and torque. Independent dyno testing has shown that by just changing out the stock pipes with the new Powerflow III two into one system, riders will experience up to a 20 percent increase in both horsepower as well as torque.
