Corsa 21125 Cat-Back Exhaust System with Twin Tips - 3.0in 4.0in

The Corsa 21125 cat-back exhaust system delivers exceptional performance and sound quality through CORSA's patented Reflective Sound Cancellation® (RSC) Technology. This innovative acoustic engineering eliminates unwanted drone while producing a deep, aggressive exhaust note that enthusiasts demand.

Key Features:

• 3.0-inch diameter mandrel-bent tubing for optimal exhaust flow
• Single side exit configuration with twin 4.0-inch polished tips
• Straight-through design maximizes airflow and reduces backpressure
• RSC® Technology provides drone-free cabin experience at highway speeds
• Computerized design ensures precise fitment and performance gains
• Improves horsepower, torque, and fuel economy over stock exhaust
• Premium construction with corrosion-resistant materials

This complete cat-back system includes all necessary hardware for installation. The mandrel-bent construction maintains consistent pipe diameter through every bend, ensuring maximum exhaust velocity and power gains. CORSA's RSC® Technology uses reflective chambers to cancel specific sound frequencies, eliminating the annoying drone common in traditional performance exhausts while maintaining an aggressive tone under acceleration.
