The Supreme SP exhaust features sophisticated exhaust note with an aesthetically functional design. The classic dual oval muffler axle-back system with large free flowing 63.5mm (2.5?) piping is comfortable to drive. Thanks to the two large SP mufflers, it has excellent sound suppression at idle and cruising. In spirited acceleration, the straight-through design makes the exhaust comes to life with a deep rich GReddy sound. Tradition double wall GReddy tips on each SP best matches the styling of the vehicle.
