Corsa 21128BLK to Dual Rear Exit Cat-Back Exhaust System with Twin Tips - 3.0in 2.75in 4.0in

The Corsa 21128BLK cat-back exhaust system delivers performance and sound engineering in one complete package. This dual rear exit system features a 3.0-inch inlet transitioning to 2.75-inch piping, finishing with aggressive twin 4.0-inch polished tips for a commanding appearance.

Key Features:

• Patented Reflective Sound Cancellation (RSC) Technology eliminates drone while creating a deep, aggressive exhaust note
• Computer-designed mandrel bent tubing maintains consistent diameter throughout bends for unrestricted exhaust flow
• Straight-through design maximizes airflow to improve horsepower, torque, and fuel economy
• Dual rear exit configuration with twin 4.0-inch diameter tips
• 3.0-inch inlet reduces to 2.75-inch piping optimized for performance
• Premium stainless steel construction for durability and corrosion resistance

Corsa's exclusive RSC technology uses precisely tuned acoustic chambers to cancel out annoying cabin drone frequencies, delivering a refined exhaust tone at cruise with an aggressive growl under acceleration. The mandrel bent design prevents flow restriction common in crush-bent systems, allowing exhaust gases to exit efficiently for measurable performance gains.
