    2020 - 2023 Chevy Corvette Stingray



    3.0" AFM Cat-Back Active Valve (NPP) with Twin 4.5" Polished Pro-Series Tips
    Xtreme Sound Level (9dB louder & 1dB quieter than Stock)
    *Deletes stock AFM Valve. Actuator integration prevents CEL. To retain AFM use Part # 21100 
    **CORSA NPP valve assembly bolts directly to stock actuator motors and is intended for use on vettes with NPP from factory.

    V8 Sound Controlled.
    The CORSA Performance C8 NPP Only exhaust puts control at the driver’s finger tips. The NPP Only C8 exhaust allows the driver to maintain full control of the C8 Corvette sound profile with fully functional CORSA Cast NPP valves that integrate seamlessly to the stock C8 actuators. Each NPP system is both Louder (+9 decibels) and quieter (-1 decibel) than that stock system and incorporates CORSA’s proprietary RSC® Technology providing a drone free driving experience while still allow the 6.2L LT2 engine to release aggressive exhaust notes under heavy acceleration. This system replaces the AFM valve with a machined simulator bracket engineered specifically to prevent an AFM Check Engine Light. Perfect for aggressive drivers who plan on driving primarily in “Track” Mode.

    No Drone Exhaust Technology
    CORSA Performance entered the exhaust category in 1998, re-writing the rulebook for what a performance exhaust should be with the launch of our revolutionary RSC® (Reflective Sound Cancellation®) Technology. RSC®Technology allows CORSA Performance the unique ability to selectively target and eliminate resonant frequencies that cause drone, by reflecting sound waves out of phase, while custom tuning the exhaust note. Since the debut of RSC® Technology in 1998 on the C5 Corvette, CORSA Performance has invested countless resources developing proprietary tools used in Perfecting the Science of Sound, resulting in world-wide recognition for high-performance, aggressive exhausts systems that eliminate drone.

    Today CORSA Performance employs multiple forms of proprietary RSC Technologies and acoustic solutions to cancel resonant frequencies that cause drone and produce the desired exhaust tone. Every CORSA Performance exhaust system manufactured takes into account OEM design, desired performance output as well as interactions of the entire Exhaust System. During the development phase an RSC Technology is chosen that best attains the desired balance of acoustics resulting in hundreds of unique designs that cover our numerous vehicle applications. Rarely are any two Exhaust Systems featuring RSC Technology the same.

    1. No Drone
    Unwanted, low frequency sound waves are diverted using specific geometry and are reversed 180 degrees out of phase.
    2. Point of Cancellation 
    Our patented sound technology is engineered to target and eliminate unwanted frequencies that cause drone.
    3. Performance Sound 
    Acoustic tuning creates an aggressive sound under acceleration that is styled to match the personality of your vehicle.
    4. Maximized HP and TQ
    A straight-through, unrestricted design reduces back pressure; increasing engine efficiency, horse power and torque.


    All CORSA exhaust systems are constructed from premium stainless steel to deliver lasting performance, sound and appearance. Easy bolt-on installation. No welding needed. All hardware and detailed instructions are included in each kit. Proudly Designed, Engineered & Manufactured in Berea, OH

    CORSA branded exhaust systems are backed by a Limited LIFETIME warranty for as long as you own your vehicle with proof of purchase.

    NOTE: Every CORSA exhaust system is engineered and designed to match the unique properties of the vehicle it is designed for to deliver perfect fitment and performance. CORSA does not recommend or recognize purchases and installation on unspecified vehicles.


    CORSA's Patented RSC Technology is designed for an AGGRESSIVE SOUND under acceleration and DRONE-FREE EXPERIENCE during cruise. Every system is engineered specifically to each vehicle without drone while cruising.
