Does This Fit Your Car?

Dinan's Free Flow Exhaust improves exhaust flow by reducing back pressure, resulting in increased power output and a great sporty sound that is civilized when you want it to be and pleasantly aggressive under harder acceleration with zero drone. 100% stainless steel construction and exacting specifications ensure that the system fits correctly using the factory hangers and will resist corrosion for years to come. A vacuum controlled butterfly valve is utilized to improve flow at wide open throttle while keeping things civilized and "drone" free throughout. The design reduces overall weight as well and features 3.5'' polished or black ceramic tips for a tasteful high performance look.
