The Invidia HS08SW1DPC catted downpipe features a divorced wastegate and high flow catalyic converter that gives your Subaru Impreza WRX / STI, Outback, Forester, or Legacy more power by removing the restrictive factory downpipe. If you are thinking of doing any exhaust modifications to your car, replacing your stock Subaru downpipe with an aftermarket is the best bang for your buck. Invidia’s downpipe is constructed of 3″ 304 stainless steel mandrel bent tubing and bolts up to any stock replacement catback or OEM exhaust. A divorced wastegate design will separate exhaust gas exiting the downpipe from the wastegate which creates a smoother more efficient exhaust flow. A smoother flow results in more HP and Torque all while keeping the exhaust fumes clean and safe for the environment. New hardware and a gasket is included for the exhaust end of this downpipe.

*Note: A tune is required when installing an aftermarket downpipe and it’s recommended to purchase a new downpipe to turbo gasket with your purchase of this product.
