GReddy 02-07 Subaru WRX/STI Evolution RS Exhaust

Constructed from polished 304 stainless steel, the GReddy Evolution RS cat-back exhaust system is built to handle the demands of your 2002-2007 Subaru Impreza WRX or STI. This system replaces the factory exhaust from the catalytic converter back, aiming to improve exhaust flow and deliver a more aggressive sound profile. The polished finish on the 304 stainless steel not only looks good but also offers solid resistance to corrosion, which is important for a component exposed to the elements.

The Evolution RS design focuses on maximizing exhaust gas velocity and volume. This can lead to a more responsive feel and a deeper, sportier exhaust note that complements the performance nature of the WRX and STI. GReddy has a long history with Subaru performance, and this cat-back system is designed to be a direct fit, meaning it bolts up to the factory connection point without requiring modifications. The piping is 2.5 inches in diameter, which is a common size for these vehicles that balances flow with maintaining good exhaust velocity.

When installing this system, you can expect a noticeable change in the exhaust tone. It's designed to be more pronounced than stock, offering a satisfying sound under acceleration. The system includes all the necessary hangers and mounting points to integrate with your vehicle's existing exhaust hangers. While this is a cat-back system, meaning it connects after the catalytic converter, it's a popular choice for owners looking to enhance both the sound and the performance potential of their Subaru.
