GrimmSpeed Exhaust Adapter for 2011 Subaru Impreza

GrimmSpeed doesn't want you to have any exhaust leaks, so they designed these exhaust adapters to use between your exhaust system and downpipe. If you have an aftermarket 3 inch downpipe and stock style 2.5 inch exhaust or an aftermarket 3 inch cat-back and stock downpipe, using the correct GrimmSpeed adapter will provide a solid mounting solution for the gasket on each side, eliminating the risk of leaks. The GrimmSpeed Exhaust Adapter even features a clean tapered transition for optimum flow (most alternatives have a abrupt step that can cause turbulence and limit power). Installation hardware and instructions are included to provide a simple worry free installation process.

Key Features:

• Virtually indestructible.
• Smooth taper does not obstruct dlow.
• Leak free precision fit.
• Simple installation.
