Corsa 21127BLK to Dual Rear Exit Cat-Back Exhaust System with Twin Tips - 3.0in 2.75in 4.0in

The Corsa 21127BLK cat-back exhaust system delivers exceptional performance and sound quality through patented Reflective Sound Cancellation (RSC) Technology. This innovative design eliminates interior drone while producing a deep, aggressive exhaust note that enthusiasts crave.

Key Features:

• Patented RSC Technology provides drone-free exhaust sound with aggressive rumble
• 3.0-inch inlet reducing to 2.75-inch dual rear exit configuration
• Twin 4.0-inch polished tips for premium appearance
• Computerized mandrel-bent tubing ensures smooth bends and maximum flow
• Straight-through design maximizes exhaust velocity and airflow
• Improves horsepower, torque, and fuel economy over restrictive factory exhaust
• Precision-engineered fitment for direct bolt-on installation
• Premium stainless steel construction for long-lasting durability

This cat-back system replaces everything from the catalytic converter back, including exhaust tubing, mufflers, and tips. The mandrel-bent design maintains consistent pipe diameter through each bend, eliminating turbulence and backpressure for optimal performance gains. Corsa's RSC Technology uses specific chamber designs and tuning to cancel out problematic frequencies, delivering the sound you want outside without annoying drone inside the cabin.
