Catalytic Converter for RAM 1500 (2015-2018) 3.6L Left & Right

Direct-Fit Catalytic Converter Assembly for 2015-2018 RAM 1500

What it Does: The Left & Right Catalytic Converter Assembly replaces degraded factory emissions equipment on the 2015-2018 RAM 1500 to restore proper exhaust velocity, eliminate catalyst efficiency trouble codes, and ensure federal emissions compliance.

The Stock RAM 1500 Catalyst Degradation

Factory exhaust converters on the DS platform succumb to long-term thermal fatigue and exhaust gas soot loading. Over time, the stock ceramic brick washcoat breaks down, causing substrate sintering, structural crumbling, and internal exhaust restriction. On the high-revving 3.6L Pentastar V6, a compromised catalyst generates excessive backpressure that chokes volumetric efficiency, drops fuel economy, and triggers persistent P0420 and P0430 DTC illuminate lights on the dash.

The Engineering Solution

Engineered to exact OEM geometry, this direct-replacement assembly features heavy-gauge stainless steel tubing and CNC-machined thick flanges designed to mate flush against factory exhaust manifolds without cutting or welding. Inside, durable ceramic honeycomb monoliths are treated with precious metal catalyst loadings to maximize conversion efficiency while reducing toxic tailpipe emissions. Mandrel-bent runners preserve continuous gas velocity, while factory-located oxygen sensor bungs and included mounting hardware guarantee an airtight, leak-free installation that withstands intense duty-cycle thermal stress.
