The Invidia R400 Gemini Single Layer Quad Black Tip Cat-Back Exhaust is a high-performance exhaust system designed for the 2015 to 2021 Subaru WRX and WRX STI models. 

This exhaust system aims to enhance both the performance and the auditory experience of your vehicle.

Key Features:

• Construction: Made from 304 stainless steel, known for its durability and resistance to corrosion.

• Piping Diameter: Features 3-inch (76mm) mandrel-bent piping, which helps in reducing exhaust restrictions and turbulence.

• Tips: Equipped with quad 4-inch (101mm) slash-cut black exhaust tips, providing an aggressive and stylish look.

• Mid-Pipe: Incorporates a resonated mid-pipe to deliver a deep, aggressive exhaust note without excessive cabin noise, especially at highway speeds.

• Fitment: Designed for direct fitment with exhaust hangers welded to OEM locations, making installation straightforward.

• Included Components: Comes with new gaskets and hardware, ensuring a complete installation package.

Performance Benefits:

• Horsepower and Torque: The increased piping diameter and smooth bends facilitate improved exhaust flow, resulting in gains of approximately 17 horsepower and 26 ft-lb of torque.

• Throttle Response: Reduces turbo lag and enhances throttle responsiveness, contributing to a more engaging driving experience.

Considerations:

If your vehicle retains the stock downpipe, an adapter (such as the one from GrimmSpeed) is required for proper fitment.
