GReddy 08-14 Subaru WRX STI/ 11-14 WRX HB Evolution RS Exhaust

The GReddy Evolution RS cat-back exhaust system is constructed from polished 304 stainless steel, a material chosen for its strength and resistance to corrosion. This system is specifically designed for the 2008-2014 Subaru Impreza WRX STI and the 2011-2014 WRX hatchback models, aiming to improve exhaust flow and deliver a more aggressive sound profile compared to the stock setup.

This cat-back system replaces the factory exhaust from the catalytic converter back, including the muffler and exhaust tips. The larger diameter piping and the free-flowing muffler design help reduce backpressure, which can lead to a more responsive engine and a noticeable change in exhaust note. The polished finish on the 304 stainless steel not only looks good but also ensures longevity, resisting rust and discoloration even in harsh weather conditions. Installation is intended to be a direct bolt-on replacement for the factory system, utilizing existing mounting points.

When installing this system, you can expect a deeper, sportier exhaust tone that is more pronounced than the factory muffler. The GReddy Evolution RS is a popular choice for Subaru owners looking for a well-built exhaust that balances performance enhancements with a refined aesthetic. It's designed to integrate seamlessly with the factory catalytic converter, making it a straightforward upgrade for your Impreza.
