AWE Touring Edition Catback Exhaust w/ Diamond Black Tips 2011-2021 STI Sedan

The AWE Catback exhaust offers perfect fitment, patented drone-canceling 180 Technology®, aggressive tip options, and a soundtrack that only AWE can deliver, all proudly engineered, designed, and manufactured in-house, in the USA. Presenting the AWE Exhaust Suite for the 2015+ STI!

The Touring Edition Catback is for drivers who like their BOXER rumble to be deep, hearty, and full of crackles all without any interior drone at cruising speeds. A direct bolt-on, full 3” straight-through design with a resonated mid section and tailored mufflers in the rear, the Touring Edition acts as the sophisticated, drone-free member of the STI exhaust suite. If you’re looking to liven up your commute while retaining civil in-cabin characteristics, this version is for you.

Thanks to the design and construction of 180 Technology® resonators, the internals will not break down and degrade over time causing tone change. Full-bodied rumble for life from the point of installation.

This configuration provides the best ratio of interior refinement and exterior rumble on the market.
