Motordyne Advanced Resonance Tuning (ART test pipes) for the HR engine

ADVANCED RESONANCE TUNING (ART)

ART pipes for increased power and torque without the drastic increase in loudness normally associated with test pipes.   ART pipes provide the quietest, smoothest, deepest sound of any test pipe while greatly reducing or eliminating rasp and drone.  The difference in sound is not subtle.  They’re not conventional test pipes. They’re ART pipes!
