Corsa Sport Axle Back Exhaust C6 Corvette (2009-2013)

Give your 2009–2013 C6 Corvette a deeper, more refined V8 exhaust note with the CORSA Sport 2.5" Axle-Back Exhaust System, available with Polished Stainless Steel (21011) or Black PVD (21011BLK) 4.5-inch Pro-Series tips.

Designed specifically for the 6.2L LS3-powered C6 Corvette, the CORSA Sport provides a noticeable increase in volume and character without stepping up to the more aggressive Xtreme sound level. It's an excellent choice for a street-driven Corvette where you want to hear more of the LS3 during acceleration while maintaining comfortable highway manners.

CORSA's signature Reflective Sound Cancellation® (RSC®) technology is engineered to eliminate unwanted cabin drone while allowing the exhaust to come alive under throttle. The system features 2.5-inch exhaust tubing, a dual rear exit, and massive quad 4.5-inch dual-wall Pro-Series tips for a substantial visual upgrade at the rear of the car. CORSA reports up to 12 horsepower, 13 lb-ft of torque, 35% increased exhaust flow, and approximately 10 lbs of weight savings for this C6 axle-back platform.

Why Upgrade?

The factory exhaust on an LS3-powered C6 keeps the Corvette relatively subdued, particularly during normal street driving. The CORSA Sport is ideal for an owner who wants more V8 character without turning the car into an excessively loud cruiser.

Compared with CORSA's Xtreme system, the Sport sound level is the more balanced street-oriented choice. You still get a deeper cold start, significantly more presence under acceleration, and a stronger exhaust note as the LS3 moves through the RPM range, but with a more restrained overall volume.

The real advantage is CORSA's approach to controlling drone. Rather than simply adding louder mufflers, CORSA engineers its exhaust systems around the frequencies produced by the specific vehicle. That makes the Sport an excellent option for a C6 that's driven regularly, taken on longer trips, or used as a weekend car where highway comfort still matters.

Choose 21011 Polished for a clean, classic Corvette look or 21011BLK Black PVD for a stealthier finish that works especially well with black wheels, carbon fiber, and other dark exterior accents.

Give your LS3-powered C6 the deeper V8 sound it deserves with CORSA Sport—aggressive when you get on the throttle, refined when you're cruising, and available with polished or Black PVD 4.5-inch tips.
