Frequently Asked Questions
What is the COR21002BLK?The Corsa COR21002BLK is a Sport 3-inch axle-back exhaust for the 2018-2023 Ford Mustang GT Fastback 5.0L, featuring dual black PVD-coated tips and RSC drone-free technology in a direct bolt-on package.
What is the difference between an axle-back and a cat-back?An axle-back system replaces only the rear muffler and tip section from the rear axle rearward. A cat-back replaces everything from the catalytic converter back. Axle-back systems are simpler to install and typically cost less, while cat-backs offer more flow improvement.
Does the COR21002BLK drone at highway speeds?No. Corsa's RSC technology eliminates highway drone on the COR21002BLK while preserving the Sport exhaust note on acceleration.
Is this compatible with Ford's active exhaust?Yes. The COR21002BLK works with the factory active exhaust valve system on equipped 2018-2023 Mustang GT models.
Does the COR21002BLK retain the factory midpipe?Yes. As an axle-back system, the COR21002BLK bolts onto the factory midpipe and retains all upstream components including the factory X-pipe or H-pipe.
Do the black tips hold up to heat?Corsa's black PVD coating resists heat discoloration far better than painted or powder-coated finishes, maintaining the dark appearance over time.
Does the COR21002BLK need a tune?No. As a cat-back and axle-back replacement, it does not affect engine management or require ECU recalibration.
What warranty does the COR21002BLK carry?Corsa Performance provides a limited lifetime warranty against defects in materials and workmanship on all exhaust systems including the COR21002BLK.
