Corsa 21018 2.75" Cat-Back Dual Rear Exit Exhaust System

The Corsa 21018 cat-back exhaust system features a 2.75-inch mandrel-bent construction designed to replace your factory exhaust from the catalytic converter back. This dual rear exit configuration delivers improved exhaust flow and reduced backpressure for noticeable performance gains across the powerband.

Reflective Sound Cancellation (RSC) Technology:

Corsa's patented RSC technology uses precisely engineered acoustic chambers to eliminate exhaust drone at highway speeds while delivering an aggressive, performance-oriented sound under acceleration. Unlike traditional muffler designs that restrict flow to reduce sound, RSC cancels unwanted frequencies through wave interference, maintaining maximum performance while controlling noise.

Key Features:

• 2.75-inch mandrel-bent stainless steel tubing for maximum flow
• Dual rear exit configuration for balanced exhaust flow
• Patented RSC technology eliminates drone during cruise
• Aggressive exhaust note under acceleration
• Direct bolt-on installation with factory mounting points
• No tips included - designed for custom tip installation or sleeper aesthetic
• Precision-engineered for specific vehicle application

This system is engineered to deliver both performance and sound quality without compromise. The mandrel-bent construction maintains consistent pipe diameter through bends, eliminating turbulence and maximizing exhaust velocity. Corsa systems are designed, tested, and manufactured in the USA with premium materials for long-lasting durability and performance.
