Description

The Dinan D660-0036 is a 100% stainless steel axle-back exhaust system designed to improve flow, reduce back pressure, and increase power output. It features a sporty sound that is civilized at idle and aggressive under acceleration, with zero drone. A vacuum-controlled butterfly valve helps optimize flow. The system is lighter than stock and uses factory hangers. Available with 3.5'' polished or ceramic black tips.
