The COBB x Korsh by SSI engine back package combines COBB's proven catback with Korsh by SSI equal length headers and downpipe for maximum flow, an aggressive tone and strong power gains from the engine all the way to the rear bumper.

• Weight Reduction – Lighter than the factory exhaust components.
• Sound – Deep, aggressive exhaust note without drone.
