Just what I needed! November 17, 2015
Reviewer: jeffrey browning from Las Vegas, NV United States  
This pipe not only extends the RPM range of my motor for a bit more top end(29.9mph to 34.3mph). but even more important is what happened to the low end torque. The engine now takes over at 5-6mph and chugs easily, instead of 10mph with a struggle! I am very pleased.
