Frequently Asked Questions
What is the CORSA 14470?The CORSA 14470 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 polished Pro-Series tips and CORSA's RSC technology for maximum performance sound without highway drone.
Does the 14470 fit all 2009-2013 C6 Corvette trims?The CORSA 14470 fits the 2009-2013 Corvette C6 Z51 and the 2010-2013 Grand Sport with the 6.2L LS3 V8. It does not fit the Z06 (LS7) or ZR1 (LS9), which use different exhaust configurations.
What is the difference between 14469 and 14470?The 14469 fits the 2005-2008 C6 with the 6.0L LS2 engine, while the 14470 fits the 2009-2013 C6 with the 6.2L LS3. Both are Xtreme axle-back systems with the same sound level and RSC tuning, built for their respective engine generations.
Is the Xtreme level suitable for daily use?The Xtreme level is CORSA's most aggressive sound tuning. RSC technology ensures there is no drone at highway cruise, making it usable for daily driving for enthusiasts who want maximum exhaust sound under throttle.
Does the 14470 require cutting or welding?No. The CORSA 14470 is a direct bolt-on axle-back replacement using factory hanger positions. No cutting, welding, or modification is required.
What is the difference between 14470 and 14470BLK?Both are identical Xtreme-level axle-back systems with the same RSC tuning. The 14470 uses polished stainless tips; the 14470BLK uses matte black PVD-finished tips.
Does this affect the factory warranty?Aftermarket exhaust systems may affect portions of the powertrain warranty related to emissions. Consult your dealer. CORSA provides its own limited lifetime warranty on the 14470.
How is this installed?The CORSA 14470 installs in under 2 hours using basic hand tools. It bolts to the factory axle-back connection points using factory hanger positions with no cutting or welding needed.
