Xtreme Axle-Back Exhaust with Polished Pro-Series Tips for C6 Corvette

The CORSA 21012 Xtreme axle-back exhaust is engineered for the 2008–2013 Chevrolet Corvette C6 equipped with the 6.2L LS3 engine. This system replaces the factory rear exhaust section with a 2.5-inch dual rear-exit layout and finishes with quad 4.5-inch polished Pro-Series tips for a bold, high-impact rear appearance.
