MagnaFlow Conv Direct Fit OEM 2004 Dodge Dakota Underbody

For the underbody catalytic converter position on your 2004 Dodge Dakota, MagnaFlow 4551027 is a CARB compliant direct-fit replacement that covers both the 3.7L V6 and 4.7L V8 engine options. It interchanges with OE parts 5202 1978AA and 5202 1978AB, so it drops into the factory location without modification.

MagnaFlow constructs this converter with 16-gauge 409 stainless steel tubing and mandrel bends that match the OE pipe routing under the truck. The spun body uses a single laser fusion weld, and 308 stainless steel MIG welds secure the pipe joints. A Torca AccuSeal exhaust clamp is included, providing 360-degree even clamping force to prevent pipe distortion. The stamped collector design maintains consistent exhaust flow through the converter.

No cutting or welding is needed for installation. On a 2004 Dakota, the factory hardware has had over two decades of exposure to road conditions, so the included Torca clamp is a welcome addition -- it provides a secure connection with fresh parts. This converter meets California Air Resource Board standards and is legal in all 50 states. Confirm your vehicle's Executive Order and Engine Family Number match before installing.
