C6 Corvette Z06 CORSA Xtreme Axle-Back Exhaust 21077
Upgrade your 2006–2013 C6 Corvette Z06 with the CORSA 21077 Xtreme axle-back exhaust system, engineered for owners who want the most aggressive CORSA sound profile without interior drone. Designed specifically for the 7.0L LS7-powered Z06, this system delivers maximum volume, improved flow, and race-inspired tone while remaining street-friendly.
The 21077 features a 3.0-inch straight-through axle-back design constructed from premium 304 stainless steel. CORSA lists airflow improvements of approximately 35% over stock, supporting sharper throttle response and real-world power gains. The system exits through 4.5-inch quad polished Pro-Series tips, filling the factory Z06 rear fascia with an aggressive, OEM-plus appearance.
CORSA’s patented Reflective Sound Cancellation® (RSC®) technology acoustically tunes exhaust pulses to eliminate unwanted resonance and cabin drone, allowing the exhaust to remain calm at highway cruise while delivering an unmistakable Xtreme scream at wide-open throttle.
