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

Give your 2009–2013 C6 Corvette the aggressive exhaust note the LS3 deserves with the CORSA Xtreme Axle-Back Exhaust System. Designed specifically for the 6.2L LS3-powered C6, the Xtreme system delivers CORSA's most aggressive sound level with a substantially louder, deeper exhaust note under acceleration while maintaining comfortable cruising characteristics.

CORSA's signature Reflective Sound Cancellation® (RSC®) technology targets the frequencies responsible for unwanted cabin drone without relying on restrictive muffler designs. The result is an aggressive exhaust note during cold starts, acceleration, and high-RPM driving without the persistent highway drone associated with many loud aftermarket exhaust systems.

The system features 2.5-inch mandrel-bent stainless steel tubing and oversized 4.5-inch dual-wall Pro-Series exhaust tips, available in your choice of Polished Stainless Steel or Black PVD. CORSA reports gains of up to 12 horsepower and 13 lb-ft of torque, a 35% increase in exhaust flow, and approximately 10 lbs of weight savings compared with the factory exhaust.

Why Upgrade?

The LS3 is one of the defining characteristics of the later C6 Corvette, but the factory exhaust suppresses much of the sound that makes a naturally aspirated 6.2L V8 enjoyable. The CORSA Xtreme is designed for the owner who doesn't want a subtle change—they want their Corvette to sound significantly more aggressive.

What separates the CORSA system from a basic muffler delete or inexpensive axle-back is its approach to sound control. Instead of simply adding volume, CORSA uses RSC® technology to control the frequencies that create unwanted cabin resonance. You get the aggressive cold starts, hard-acceleration sound, and high-RPM LS3 exhaust note you want without intentionally adding constant low-frequency drone on the highway.

The choice between Polished Stainless Steel and Black PVD tips also allows you to tailor the appearance to the car. Polished tips provide a classic Corvette performance look, while Black PVD tips create a more modern, understated appearance that pairs especially well with black wheels, carbon fiber, and other dark exterior accents.

With aggressive sound, larger 4.5-inch tips, increased exhaust flow, reduced weight, and CORSA's proven RSC® technology, this is one of the most complete bolt-on exhaust upgrades for an LS3-powered C6 Corvette.
