Frequently Asked Questions
What is the CORSA 14470BLK?The CORSA 14470BLK is a 2.5-inch Xtreme axle-back exhaust system for the 2009-2013 Chevrolet Corvette C6 6.2L LS3 V8, featuring twin 3.5-inch matte black PVD Pro-Series tips and CORSA's RSC technology for maximum performance sound without highway drone.
What is the difference between 14470 and 14470BLK?Both are identical Xtreme-level axle-back systems with the same RSC tuning and 2.5-inch T304 stainless construction. The only difference is tip finish: the 14470 uses polished stainless tips, while the 14470BLK uses matte black PVD-coated tips.
Does the 14470BLK fit the 2010-2013 Grand Sport C6?Yes. The CORSA 14470BLK fits both the 2009-2013 Corvette C6 Z51 and the 2010-2013 Grand Sport, both with the 6.2L LS3 V8 engine.
Will the matte black tips hold up on a track-driven C6?Yes. The matte black PVD coating on T304 stainless steel is heat-resistant and corrosion-resistant, designed to hold up under normal road and occasional track use. Regular cleaning helps preserve the finish.
Is the Xtreme sound level drone-free?Yes. Despite being CORSA's loudest tuning, the 14470BLK uses RSC technology to cancel the low-frequency resonance that causes drone at highway speeds. It is aggressive under throttle and completely refined at cruise.
Does the 14470BLK require cutting or welding?No. The CORSA 14470BLK is a direct bolt-on axle-back replacement. It installs using factory hanger positions with no cutting, welding, or modifications required.
Does this fit the C6 Z06?No. The 14470BLK is designed for the 6.2L LS3 engine. The C6 Z06 uses the 7.0L LS7 engine and requires a separate exhaust application.
What is CORSA's warranty on the 14470BLK?CORSA provides a limited lifetime warranty on the 14470BLK against defects in materials and workmanship when purchased from an authorized dealer and used in normal on-road conditions.
