C8 Corvette Stingray Corsa Xtreme Cat Back Exhaust 21102 - No NPP

C8 Corvette Stingray CORSA 21102 Non-NPP Cat-Back Exhaust with Polished Pro-Series Tips

Deleting the mufflers takes the last restriction out of the C8 exhaust path and leaves one volume behind it. The CORSA Non-NPP Cat-Back Exhaust, part 21102, is a 3.0 inch cat-back with a custom X-pipe for the 2020-2026 C8 Corvette Stingray coupe and HTC convertible built without RPO NPP, the factory performance exhaust. What it takes out, and what it leaves alone, are both worth knowing before you order.

The system runs a custom X-pipe back to four 4.5 inch polished Pro-Series tips and deletes the mufflers on the way, so your Stingray is loud from the first cold start and stays there. The CORSA AFM valve assemblies bolt directly to your factory actuator motors, so the AFM valve function your Stingray was built with stays with the system. There is no quiet mode to fall back on and no RSC no-drone hardware in the pipes, so the volume you hear in the driveway is the volume you get on the interstate.

Benefits

• The mufflers and their hangers come off the back of the car, a saving of 25 pounds
• A 3.0 inch path with no mufflers in it flows more than the factory system, worth 18 horsepower and 16 lb-ft
• Volume is fixed at 13 decibels over stock, every start, every drive
• The CORSA AFM valve assemblies bolt directly to your factory actuator motors, which is what separates this system from the valve-delete configuration
• Four polished Pro-Series tips fill all four fascia openings, and they come off the system on their own if you change the finish later
• Dual wall tip construction keeps the outer wall cooler than a single wall tip, so the polish holds up

What to Expect

The system bolts into the factory cat-back position on the original hangers. Nothing is cut and nothing is welded, so it comes back off as easily as it went on, and the polished tips unbolt from the system without disturbing the rest of it.

Professional installation is recommended. Because of GM factory tolerances some C8 Corvettes want the GM valve relearn sequence afterwards, GM Document ID 5406413. Ask your installer to run it if a check engine light shows up.

Important Exhaust Notes

• Check your RPO NPP status before you order. This system is for a Stingray built without NPP, the factory performance exhaust option, and it will set a check engine light on a 2021 or newer car that has NPP.
• You give up the quiet mode. There is no drive-mode sound control on this system and nothing to switch.
• RSC no-drone technology is not part of this configuration.
• This is a bolt-up system: it installs at the factory hangers and mounting locations with the hardware supplied in the kit.

Use Overview
