This third generation of the Powerflow series is the most powerful 2 into 1 ever made. Samson took some old engineering from the first Powerflow system and implemented it into their newly engineered Powerflow III. The engineering implemented into the Powerflow III is from an accumulation of years of research on how power is generated. The power is generated through a series of chambers (each of which is called a "Power Chamber") which help condense and intensify exhaust flow and results in extremely high horsepower and torque. The results are phenomenal. With the new system you can take a stock Harley-Davidson and turn it into a high performance motorcycle by simply changing out the pipes.
With removable baffles, and removable 4" end caps.
Notes: This Samson exhaust system is not intended for use on any noise or pollution controlled vehicle (except those used exclusively in organized and sanctioned racing events) or when the installation of the same would be in violation of state or federal laws or regulations governing noise or air pollution requirements.
