Corsa 21331 Sport Cat-Back Exhaust System

The Corsa 21331 Sport Cat-Back Exhaust System delivers an aggressive, performance-tuned exhaust note engineered using Corsa's patented Reflective Sound Cancellation (RSC) technology. This system is designed to eliminate unwanted drone at highway speeds while producing a deep, throaty exhaust tone during acceleration — giving you the performance sound you want without the cabin fatigue you don't.

Corsa Performance exhausts are constructed from premium 304 stainless steel for maximum corrosion resistance and long-term durability. The Sport series is tuned to provide a noticeable increase in exhaust flow over the factory system, contributing to improved throttle response and a more engaging driving experience.

Key Features:

• Patented Reflective Sound Cancellation (RSC) technology eliminates interior drone
• Premium 304 stainless steel construction for superior corrosion resistance
• Sport-tuned exhaust tone — aggressive under throttle, refined at cruise
• Direct bolt-on, no cutting or welding required for installation
• Polished stainless steel exhaust tip(s) included

The Corsa 21331 is a complete cat-back exhaust system, replacing everything from the catalytic converter outlet back to the exhaust tips. Installation is straightforward with included hardware and requires no permanent modifications to the vehicle.
