Description

A lightweight, high-flow, single-exit full titanium exhaust system weighing 17 lbs (with resonator), approximately 22 lbs lighter than the OE exhaust. Features 3.0" mandrel-bent piping, a high-flow straight-through muffler, and a 4.5" slant-cut tip. Designed for optimal flow to reduce restriction and enhance performance and sound. The resonated version helps reduce overall loudness. Hand-crafted with high-quality TIG welding. Installation requires removal of the factory donut gasket.
