GReddy 11-14 Subaru STI Sedan Evolution GT Exhaust

What you get with this GReddy Evolution GT exhaust system is the complete cat-back assembly, designed specifically for the 2011-2014 Subaru Impreza STI Sedan. This means the piping from the catalytic converter back to the rear of the car, including the mufflers and exhaust tips, is all included in one package. It’s built to replace your factory exhaust, aiming to improve the way your engine breathes and sounds.

This Evolution GT system is constructed from polished stainless steel, which is known for its strength and resistance to corrosion, especially important for exhaust components that deal with heat and moisture. The piping diameter is 3 inches, a step up from the stock setup, which helps reduce backpressure and allows exhaust gases to exit more freely. This improved flow can lead to a more responsive feel from the engine, particularly in the mid to upper RPM range. The mufflers are designed to give your STI a deeper, more aggressive exhaust note without being overly loud or droney for daily driving. The polished stainless steel tips give the rear of the car a clean, performance-oriented look.

When installing this cat-back system, you'll typically be bolting it directly to your existing catalytic converter. No welding is usually required, making it a more straightforward installation process. It’s a solid option if you’re looking to enhance the performance and sound of your 2011-2014 Impreza STI Sedan and want a well-built exhaust system that will last.
