The Corsa 21128 cat-back exhaust system delivers a performance upgrade with a dual rear exit configuration, transitioning from 3.0-inch inlet to 2.75-inch piping and finishing with aggressive twin 4.0-inch polished tips.

Key Features:

• Patented Reflective Sound Cancellation® (RSC) Technology eliminates interior drone while producing a deep, aggressive exhaust note
• Precision computerized mandrel-bent tubing maintains consistent diameter throughout bends for unrestricted airflow
• Straight-through design maximizes exhaust flow for improved horsepower, torque, and fuel efficiency
• Dual rear exit routing with twin 4.0-inch diameter tips for bold styling
• Engineered to deliver performance gains without sacrificing daily drivability

Corsa's RSC technology uses precisely tuned internal chambers to acoustically cancel specific drone frequencies, allowing you to enjoy an aggressive exhaust tone during acceleration without the fatigue of highway drone. The mandrel-bent construction ensures smooth, consistent pipe diameter for maximum flow efficiency compared to crush-bent alternatives.
