Combine the exhaust manifold and catalytic converter into a single bolt-on unit with the DORMAN exhaust manifold with integrated catalytic converter (679-575), a direct-fit replacement for the 2019-2022 RAM 1500 with the V6-3.6L engine. It serves the right-side exhaust, routing gases from the cylinder head through a ceramic-substrate converter that helps reduce emissions, with a midbed oxygen sensor port feeding the engine management system.
Also known as a manifold converter, this one-piece stainless steel unit is built to the original part's fit and performance on the listed application, with a roughly 31 in overall length and flanged inlet and outlet connections for a straightforward swap.
- Integrated design: one-piece stainless steel manifold and converter with a ceramic substrate.
- Convenient kit: includes an inlet gasket plus downpipe (outlet) hardware — 2 bolts, 2 nuts and 2 washers; inlet mounting hardware, clamps and hangers are not included.
- Sensor ready: midbed oxygen sensor port.
This is a pre-converter that is not CARB certified or New York certified, so it is not legal for sale or use in California, New York, or other states requiring CARB-compliant converters — confirm it is approved for use in your state. Made in the United States.
