GReddy 15+ Subaru WRX/STi Revolution RS Exhaust

This is the GReddy Revolution RS cat-back exhaust system for your 2015-2020 Subaru WRX or WRX STI. It replaces the factory muffler and piping from the catalytic converter back, aiming to improve exhaust flow and give your car a more aggressive sound. If you're looking to change the exhaust note and potentially free up a little bit of power, this is a solid option to consider.

GReddy is well-known for its performance exhaust components, and the Revolution RS line is designed with both sound and performance in mind. This system is constructed from polished stainless steel, which helps resist corrosion and looks good under the car. The muffler features a straight-through design internally to minimize backpressure, allowing exhaust gases to exit more freely than the stock setup. You'll notice a deeper, sportier tone, especially when you get on the throttle. Installation is typically a bolt-on affair, replacing the factory system without requiring welding or major modifications, though you should always refer to the manufacturer's instructions for the most accurate installation details.

This cat-back system is designed to fit the 2015 through 2020 model years of the Subaru WRX and WRX STI. It's a popular choice for owners who want a noticeable change in their car's exhaust sound and appearance. While it's designed for improved flow, keep in mind that significant power gains are usually achieved when paired with other engine modifications like a tune and intake. This exhaust focuses on delivering a satisfying sound and a well-built exhaust path.
