Direct-Fit Rear Catalytic Converter for 2008-2010 Dodge Caravan (RT)

What it Does: The Rear Catalytic Converter for the 2008-2010 Dodge Caravan restores factory exhaust flow dynamics and operational emissions reduction to eliminate P0420 diagnostic trouble codes and pass state inspections.

The Stock Dodge Caravan Catalyst Breakdown

High-mileage RT chassis minivans operating the EGF (3.3L) and EGH (3.8L) pushrod engines frequently suffer from exhaust thermal fatigue and internal catalyst washcoat degradation. Unburned hydrocarbon loading and prolonged heat cycles cause the factory ceramic honeycombs to crumble, melt, or poison the precious metal coating. This failure mode triggers persistent check engine lights (CEL), collapses interior exhaust scavenging, spikes backpressure against exhaust valves, and robs both low-end torque and fuel economy during standard driving cycles.

The Engineering Solution

This direct-fit rear catalytic converter features heavy-duty stainless steel casing designed to resist road debris corrosion and thermal expansion cracks. Internally, a dense, flow-optimized ceramic substrate is layered with an active washcoat to ensure optimal chemical conversion of hydrocarbons, carbon monoxide, and NOx emissions. Laser-aligned, OE-spec flanges and integrated hangers mount directly to factory exhaust studs without cutting, torching, or custom fabrication, ensuring clean mating with interchange numbers 643032, 20436, 47846, and 59381.
