Description

The GrimmSpeed OEM Downpipe to 3in Cat Back Adapter is a CNC machined steel adapter designed to bridge the gap between an OEM downpipe and a 3-inch cat-back exhaust system. It features a flanged design that retains the stock donut gasket, helping to prevent exhaust leaks common in modified Subarus. This adapter offers a simple bolt-on installation.
