Frequently Asked Questions

What is the COR21042BLK?

The COR21042BLK is a Corsa Performance Sport cat-back exhaust for the 2018-2020 Ford Mustang GT and Bullitt 5.0L V8, featuring 4-inch black PVD Pro-Series dual tips and Corsa's patented RSC Technology for drone-free Sport-level sound.

How does the COR21042BLK differ from COR21042?

The COR21042BLK and COR21042 are identical exhaust systems. The only difference is the tip finish: COR21042BLK has black PVD coated tips, while COR21042 has polished stainless tips.

Will the black tips hold their finish in hot exhaust conditions?

Yes. The black PVD coating is bonded at the molecular level and is specifically formulated to withstand the high temperatures found in automotive exhaust applications.

Does the COR21042BLK need a tune after installation?

No tune is required. The COR21042BLK bolts directly to the factory exhaust connection points without any engine management modifications.

Is there interior drone with the COR21042BLK?

No. Corsa's RSC Technology eliminates the resonance frequencies that cause drone, making the COR21042BLK comfortable for daily use even at highway speeds.

No. This system is not CARB compliant and is for off-highway use in California. It is legal for street use in all other US states.

Will this fit the 2021 or newer Mustang GT?
