Greddy's Supreme SP catback exhaust is a perfect compliment to any WRX or STI boxer engine. It features a midpipe resonator that keeps sound very smooth and a dual muffler setup with the perfect amount of performance sound. No droning or loud transitions through the rpm's with this setup. The twin tips sit further out than the stock tips for a perfect fitment to let people know you chose a great fitting exhaust. They sit flush and even, right in the factory bumper. 3" piping ensures that exhaust gases clear out of the engine easier which increases power and torque and lets the turbo do it's job better. The stainless steel material allows the Greddy exhaust to stay clean and durable in many different conditions. The TIG welds are very clean, strong, and visually appealing. Installation is a breeze with the included gaskets and hardware.
**INSTALLATION NOTE - If you plan on installing this Greddy exhaust setup on your Subaru WRX or STI with the stock downpipe, we recommend use of the Grimmspeed adapter located here. This will make fitment that much easier and ensure no exhaust leaks or fitment problems.
