Catalytic Converter for Chrysler Pacifica (2017-2021) 3.6L Left & Right

Direct-Fit Left & Right Catalytic Converter Set for 2017-2021 Chrysler Pacifica

What it Does: The Direct-Fit Left & Right Catalytic Converter Set replaces deteriorated factory emissions equipment on the 2017-2021 Chrysler Pacifica to restore proper exhaust scavenging, eliminate catalyst trouble codes, and ensure optimal fuel efficiency.

The Stock Chrysler Pacifica Substrate Breakdown

Under repeated thermal cycling, the factory catalytic converters on the RU platform Pacifica are prone to thermal fatigue, ceramic washcoat breakdown, and internal sintering. High operating exhaust gas temperatures produced by the Atkinson/Otto-cycle 3.6L Pentastar V6 cause the factory ceramic substrates to degrade over time, diminishing oxygen storage capacity and triggering persistent P0420 and P0430 diagnostic trouble codes. Furthermore, structural degradation within the stock converters increases exhaust backpressure, robbing the engine of combustion efficiency and causing sluggish throttle response.

The Engineering Solution

This direct-fit dual converter set is constructed with heavy-gauge, corrosion-resistant stainless steel piping and robotically welded, CNC-machined flanges that seal flat against the cylinder heads and downpipe connections. Internally, high-porosity ceramic honeycomb substrates feature an optimized noble metal washcoat designed for rapid light-off times and thorough catalytic reduction of harmful emissions. Mandrel-bent tubing guarantees uniform cross-sectional area to sustain laminar exhaust flow dynamics and recover factory horsepower, all while utilizing stock mounting points, O2 sensor bungs, and supplied hardware for an exact bolt-on installation.
