Direct-Fit Front Left & Right Catalytic Converter Set for 2019-2023 Chevrolet Blazer (C1XX)

What it Does: The Front Left & Right Catalytic Converter Set restores factory exhaust gas treatment and clears catalyst efficiency diagnostic trouble codes on the 2019-2023 Chevrolet Blazer 3.6L.

The Stock Chevrolet Blazer Catalytic Converter Degradation

Factory close-coupled manifold converters on the C1XX platform face extreme thermal cycling from the high-revving direct-injection LGX V6. Over time, internal washcoat degradation, fuel vapor blow-by, and severe heat expansion cause ceramic monolith breakdown, leading to restricted exhaust backpressure, lost fuel economy, and persistent P0420/P0430 threshold fault codes.

The Engineering Solution

Engineered as a bolt-on replacement for part numbers 641635 and 641636, this dual assembly utilizes heavy-duty 409 stainless steel tubular bodies built to survive thermal shocks. High-flow internal ceramic honeycombs loaded with robust precious metal washcoats provide efficient HC, CO, and NOx reduction without restricting exhaust velocity. Precision-machined, thick OE-style flanges ensure an airtight seal against manifold studs, while pre-threaded oxygen sensor ports accept factory O2 sensors without harness stretching or wire modification.
