Frequently Asked Questions
What is the COR21010BLK?The Corsa COR21010BLK is the black-tip version of the Xtreme 2.5-inch axle-back for the 2005-2008 Corvette C6 6.0L and 6.2L, featuring twin 4.5-inch black PVD-coated tips and RSC drone-free technology.
What is the difference between COR21010 and COR21010BLK?The COR21010BLK has twin 4.5-inch black PVD-coated tips instead of polished tips. All performance specifications are identical.
Does the COR21010BLK eliminate drone?Yes. RSC technology cancels standing wave resonance at cruise RPM, making the COR21010BLK quiet at highway speeds and loud at full throttle.
Will the black tips discolor from heat?Corsa's black PVD coating resists heat discoloration significantly better than painted or dipped finishes, maintaining the dark appearance over time.
Is the COR21010BLK compatible with the Z06?No. The C6 Z06 has a different exhaust layout. For Z06 and ZR1 applications, see the Corsa COR21077.
Does the COR21010BLK require a tune?No. It is an axle-back system that does not affect engine management.
Is this a direct bolt-on?Yes. The COR21010BLK bolts directly to the factory C6 axle-back flanges with no cutting or modifications required.
What warranty does the COR21010BLK carry?Corsa Performance provides a limited lifetime warranty on all exhaust systems including the COR21010BLK.
