Motordyne ART pipes:
Through countless hours of research and development a new path has been explored in the never ending quest for increasing horse power on the reciprocating engine. A method of directly altering exhaust harmonics for increased horsepower and torque. This is Motordyne's debut of the patent pending Advanced Resonance TuningTM. Implemented in a superior substitute for test pipes.
They're not headers. They're not test pipes. They're ART pipes!
