Frequently Asked Questions
What is the COR14991BLK?The Corsa COR14991BLK is the black-tip variant of the Sport 2.5-inch cat-back exhaust for the 2011-2021 Jeep Grand Cherokee 5.7L HEMI, featuring 4.5-inch black PVD-coated tips and RSC drone-free technology.
What is the difference between COR14991 and COR14991BLK?The COR14991BLK uses a 4.5-inch black PVD-coated tip instead of the polished tip on the COR14991. All other specifications are identical.
Will the black tips on the COR14991BLK hold their color?Corsa's black PVD coating resists heat discoloration and surface oxidation significantly better than painted finishes, maintaining the dark appearance over time.
Does the COR14991BLK fit the 3.6L Grand Cherokee?No. The COR14991BLK is engineered specifically for the 5.7L HEMI V8. The V6 models have different exhaust routing and flange configurations.
Is there drone at highway speeds with the COR14991BLK?No. Corsa's RSC technology eliminates drone at steady cruise RPM, making the COR14991BLK completely comfortable for long daily commutes and road trips.
Does the COR14991BLK require a tune?No. The COR14991BLK is a bolt-on cat-back replacement that does not affect ECU programming or emissions systems.
Does this exhaust void my warranty?Under the Magnuson-Moss Warranty Act, a manufacturer cannot void your vehicle warranty simply because you installed an aftermarket part unless they can prove the part caused the issue. Consult your dealer and legal advisor for specifics.
What warranty does Corsa offer?Corsa Performance provides a limited lifetime warranty against manufacturing defects on all exhaust systems including the COR14991BLK.
