Adding a 3″ cat back exhaust to your ride? This is the perfect adapter for you! Most 3″ exhausts will use a 3″ flat gasket. The factory exhaust of your Subaru has a donut gasket. This is a common leak area when adding a cat back exhaust. This is a must have add on for any cat back installation. If your factory DP donut gasket has seen better days make sure to grab another new donut gasket in the Gaskets section!
