3-Inch to 2.5-Inch Exhaust Adapter

Exhaust leaks can be a common and frustrating issue, especially when attempting to connect an aftermarket 3-inch downpipe to an OEM 2.5-inch exhaust system. The GrimmSpeed downpipe adapter provides a robust solution to eliminate these leaks. Constructed from indestructible steel using a CNC laser cutting process, this adapter is built for longevity. It is flanged to accept an OEM donut gasket, facilitating a secure connection. The adapter's flared end, measuring just under 3 inches, is engineered to prevent any reduction in exhaust flow, unlike some competing products. Installation is a simple bolt-on process, and all necessary hardware is included. However, it is important to note that the GrimmSpeed 3-inch gasket and the OEM Subaru donut gasket are sold separately. This adapter is exclusively intended for connecting an aftermarket 3-inch downpipe to an OEM-style cat-back exhaust and cannot be used in reverse.
