Frequently Asked Questions
What is the COR21077?The COR21077 is a Corsa Performance Xtreme axle-back exhaust with dual polished 4-inch Pro-Series tips, designed for the 2006-2013 Chevrolet Corvette C6 Z06 7.0L LS7 and 2009-2013 ZR1 6.2L LSA. It uses patented RSC Technology for aggressive Xtreme sound without interior drone.
Does the COR21077 fit the base C6 Corvette?No. The COR21077 is specifically designed for the C6 Z06 and ZR1. For the base C6 Corvette, a different Corsa part number is required due to differences in rear fascia and exhaust routing.
Is the Xtreme level too loud for daily driving?The Xtreme level is Corsa's most aggressive sound. Corsa's RSC Technology manages drone, making the COR21077 more livable than non-RSC alternatives at comparable sound levels. Many Z06 and ZR1 owners find the Xtreme level appropriate for both track and daily use.
Will the COR21077 affect Z06 or ZR1 performance?The axle-back design replaces only the mufflers and tips, not the mid-pipes or headers. Any performance gain is secondary to the primary benefit of improved exhaust sound. For larger power gains, combine with a full cat-back system.
Does the COR21077 require a tune?No. As an axle-back system, the COR21077 does not alter exhaust flow significantly enough to require an ECU retune.
Is there a black tip version of the COR21077?We recommend contacting us to verify current black tip variants for the C6 Z06 and ZR1 platform if that finish is preferred.
What warranty does Corsa offer?Corsa Performance backs the COR21077 with a limited lifetime warranty covering manufacturing defects in materials and workmanship.
Is the COR21077 CARB compliant?No. This system is not CARB compliant and is for off-highway use in California. It is street legal in all other US states.
Installation Instructions
- Safely raise the Corvette on a lift or jack stands and allow the factory exhaust to cool completely.
- Locate the factory axle-back muffler connection points behind the rear axle.
- Disconnect the factory muffler from the mid-pipe connection point.
- Remove all factory hanger connections and lower the stock mufflers from the vehicle.
- Install the Corsa muffler assembly and connect to the mid-pipe using the provided hardware.
- Secure all hanger points and align the polished 4-inch tips evenly in the rear fascia openings.
- Tighten all connection hardware and verify hanger positions are secure.
- Start the engine and inspect for exhaust leaks before driving.
