Free Your 2019-2021 Ram 1500 Crew Cab from Factory Muffled Sound
The Corsa Performance COR21044 Resonator Delete Kit removes the factory resonators on your 2019-2021 Ram 1500 Crew Cab Long Bed and replaces them with smooth, straight-through 3-inch T304 stainless steel tubing.

Frequently Asked Questions
What is the COR21044?The COR21044 is a Corsa Performance 3-inch resonator delete kit designed for the 2019-2021 Ram 1500 Crew Cab with the 6-foot 4-inch Long Bed. It replaces the factory resonators with straight-through T304 stainless steel tubing for a deeper, more aggressive HEMI exhaust note.
Will the COR21044 fit my Ram 1500 with a Short Bed?No. The COR21044 is specifically sized for the Crew Cab Long Bed configuration with a 6 ft 4 in bed. Short Bed or Quad Cab configurations require a different part number. Verify your exact bed and cab combination before ordering.
Does the COR21044 work with the factory Ram exhaust or only Corsa systems?The COR21044 is compatible with both the factory Ram exhaust system and Corsa cat-back systems, making it a versatile upgrade regardless of your current exhaust configuration.
How much louder will my Ram get with the COR21044 installed?The resonator delete will noticeably deepen and amplify the HEMI exhaust note, particularly during acceleration and at lower RPMs. The exact increase in volume varies by engine and exhaust configuration, but most owners report a substantial improvement in sound character.
Will removing the resonators cause a check engine light?No. The resonators on the Ram 1500 are passive sound-tuning devices with no electronic sensors. Removing them with the COR21044 will not trigger a check engine light or affect any emissions sensors.
Does the COR21044 require professional installation?Most experienced DIY installers can complete the resonator delete in two to three hours with basic hand tools. Professional installation is an option if you prefer it, but is not required.
Is the COR21044 legal in California?This resonator delete kit does not meet CARB requirements for street use in California. It is legal for street use in all other US states.
Does Corsa back the COR21044 with a warranty?Yes. Corsa Performance covers the COR21044 with a limited lifetime warranty against defects in materials and workmanship.
Installation Instructions
- Safely raise the Ram 1500 on a lift or jack stands and allow the exhaust to cool completely.

- Disconnect the exhaust at each resonator connection point.
- Remove the factory resonators from the vehicle.
- Insert the Corsa resonator delete pipe sections into position.
- Connect and secure all connection points with the provided clamps and hardware.
- Start the engine and inspect all connections for exhaust leaks before driving.
