Product Description

This downpipe adapter for the Subaru WRX, STI & Legacy GT is the perfect solution to the problem of matching a 3" aftermarket downpipe to a catback system that uses the stock 2.5" taper. The 3" downpipe adapter plate allows you to install the factory donut gasket on the end of any 3" flat flange downpipe to ensure a perfect seal with the factory or any other 2.5" tapered catback exhaust system (Cobb Tuning, Blitz, Borla & Greddy just to name a few).

Requires OEM donut gasket
Longer bolts may be necessary to connect the downpipe to the midpipe
