CORSA NPP Double Helix Exhaust System – 6th Gen Camaro SS / ZL1

Premium CORSA NPP exhaust system for 6th gen Camaro SS / ZL1, in excellent condition with only ~5,000 miles of use. Includes the discontinued Double Helix secondary cat-delete midpipe (P/N: 14788) paired with CORSA NPP active valve axle-back mufflers (P/N: 14789) for aggressive performance sound with full factory valve control. Removed from a ZL1 1LE that was never driven in rain, making this a rare premium setup for serious Camaro builds.
