Aftermarket 3-Inch Downpipe to OEM Catback Adapter

GrimmSpeed Aftermarket 3-Inch Downpipe to OEM Catback Adapter (077044)

Per GrimmSpeed, exhaust leaks are an all-too-common issue on modded Subarus, and the most guaranteed leak comes from running an aftermarket 3in downpipe to an OEM or OEM-like 2.5in exhaust. This adapter is GrimmSpeed's solution to that leak.

Per GrimmSpeed, the adapter is cut from steel and hand welded, and works with both flat style gaskets and donut gaskets. One end is flared out to just shy of 3in so the adapter does not block flow.

Quick specs (per GrimmSpeed)

• Flared adapter creates a smooth transition from your 3in downpipe to your OEM midpipe
• Flanged for the OEM donut gasket
• Steel CNC laser cut construction
• Simple bolt-on installation with included hardware
• Flared end will not obstruct exhaust flow

Notes (per GrimmSpeed)

• GrimmSpeed 3in gasket and OEM Subaru donut gasket are sold separately
• Intended only for connecting an aftermarket 3in downpipe to an OEM-style catback; it cannot be used in reverse
