GReddy 2015 Subaru STI/WRX Sedan Supreme SP Exhaust

Built from polished 304 stainless steel, this GReddy Supreme SP cat-back exhaust system is a solid option for your 2015-2020 Subaru WRX or STI sedan. The system is designed to replace the factory exhaust from the catalytic converter back, offering a more aggressive sound and improved exhaust flow compared to the stock setup. The polished finish not only looks good but also helps resist corrosion, keeping your exhaust looking sharp for longer.

The Supreme SP features a dual muffler design with straight-through mufflers and a larger pipe diameter than stock. This setup is tuned to produce a deep, sporty exhaust note without excessive drone at cruising speeds, a common concern with aftermarket exhausts. The larger piping and less restrictive mufflers help the engine breathe more freely, which can lead to a slight improvement in throttle response and overall performance. The system includes all the necessary hangers and mounting points to bolt directly onto the factory location, making installation straightforward for someone comfortable working with exhaust components.

This cat-back system is a popular choice for WRX and STI owners looking to enhance the sound and aesthetics of their vehicle. It's a well-built exhaust that balances performance with a refined driving experience. When installing, ensure all connections are properly sealed to prevent leaks and achieve the best sound and performance from the system.
