Catalytic Converter for Honda Accord (1998-2002) 2.3L

EPA-Compliant Direct-Fit Catalytic Converter for 1998-2002 Honda Accord

What it Does: Replaces degraded factory catalytic converters with an EPA-compliant ceramic substrate to eliminate P0420 fault codes and restore exhaust scavenging efficiency on 2.3L F-Series engines.

The Stock Accord Catalytic Deterioration

Factory ceramic honeycomb cores on aging 6th-generation Accords degrade over extended thermal cycling, leading to washcoat sintering, catalyst poisoning, and reduced precious metal reactivity. When the core breaks down or fractures internally, restricted exhaust gas pathways increase backpressure behind the manifold, leading to elevated exhaust gas temperatures (EGTs), sluggish throttle response, unburned hydrocarbon emissions, and persistent OBD-II fault codes.

The Engineering Solution

Built with mandrel-bent stainless steel piping and a high-flow ceramic washcoat core, this direct-fit rear converter optimizes flow dynamics while maintaining strict 49-state emissions compliance. Heavy-duty OE-style mounting flanges and automated TIG-welded joint seams resist thermal fatigue and vibration stress. Includes an integrated O2 sensor bung and direct-fit hardware to deliver a leak-free seal without cutting or custom fabrication.
