Catalytic Converter for Chevrolet Traverse (2018-2023) 3.6L Front & Rear Manifold Set

EPA-Compliant Direct-Fit Manifold Catalytic Converter Set for 2018-2023 Chevrolet Traverse (C1XX)

What it Does: The manifold catalytic converter set replaces degraded front and rear factory catalytic units on the 2018-2023 Traverse to eliminate P0420/P0430 trouble codes, restore exhaust velocity, and reduce tailpipe emissions.

The Stock Chevrolet Traverse Catalytic Substrate Degradation

Over extended heat cycles, the factory manifold converters on the C1XX platform suffer from washcoat erosion, thermal sintering, and internal ceramic core fracturing. A fouled or restricted substrate generates excessive backpressure, escalating exhaust gas temperatures and triggering spark retard on the direct-injected LFY 3.6L V6. This restriction causes persistent check engine lights (P0420/P0430), rough idle, power loss under load, and sulfur exhaust odors.

The Engineering Solution

Engineered to replace OEM part number FCE067-068X, this matched front and rear bank converter set features heavy-gauge stainless steel canister construction resistant to thermal fatigue and road corrosion. High-flow ceramic honeycomb monoliths coated with precious metal catalyst washcoats facilitate thorough oxidation of unburned hydrocarbons and carbon monoxide while neutralizing nitrogen oxides. Precision laser-cut flanges, OE-location oxygen sensor bungs, and integrated brackets allow direct bolt-on installation without cutting or custom welding.

Frequently Asked Questions & Fitment Warnings

Does this fit the C1XX Traverse?

Yes, this is a direct fit for the 2018-2023 Chevrolet Traverse equipped with the LFY engine. This EPA-compliant set is for Federal emissions vehicles only and cannot be shipped to or registered on CARB-emissions vehicles in California, Colorado, New York, or Maine.

What mechanical issues must be corrected before installing this converter set?

All active engine misfires, oil consumption issues, and coolant leaks must be repaired prior to installation to prevent immediate contamination and thermal destruction of the new catalyst substrates.

The Chevrolet Durability Standard

Engineered to handle sustained thermal cycling and highway towing demands up to the 5,000-lb limit, this manifold set maintains exhaust flow efficiency and keeps your engine running cool under heavy payload stress.
