GReddy Supreme SP Cat-Back Exhaust System 2015-2021 WRX / 2015-2021 STI

Greddy has an established name in the Import Performance scene due to the quality and results their products produce. Their cat back system has been produced using the same careful engineering practices to provide your vehicle with increased horsepower, torque, and this exhaust system will enhance that flagship rumble.

This exhaust features large dual oval mufflers and quad staggered tips in a "tucked-away" layout, for maximum muffler ground clearance. Large 76mm (3”) piping is carefully routed around the rear differential to a centralized Y-section for more even flow. This creates and improved performance with exceptional sound for both the EJ powered STI and FA powered WRX applications. The system is finished off with classic quad Supreme SP 89mm laser engraved GReddy tips.

Note: A OEM Downpipe to 3in Cat Back Adapter may be necessary if the diameter of the new cat-back exhaust systems piping is different from the stock system, or if there are compatibility issues between the new components and the existing downpipe.
