Catalytic Converter for Honda Odyssey (2008-2016) 3.5L

Direct-Fit Bank 2 Catalytic Converter for 2008-2016 Honda Odyssey

What it Does: Replaces a degraded or clogged front manifold catalytic converter to clear P0420/P0430 diagnostic trouble codes and restore factory exhaust velocity.

The Stock Odyssey Manifold Catalyst Deterioration

The front Bank 2 manifold catalytic converter on the transverse-mounted J35 engine operates under extreme thermal cycling and direct exhaust gas pulses immediately downstream of the cylinder head. Over extended mileage, the factory washcoat degrades and the internal ceramic washcoat suffers thermal sintering from high exhaust gas temperatures. This degradation leads to reduced oxygen storage capacity, catalyst substrate breakdown, and restricted exhaust gas scavenge, ultimately triggering diagnostic trouble codes, hesitation under load, and elevated tailpipe emissions.

The Engineering Solution

This replacement converter utilizes a high-grade 409 stainless steel housing designed to resist thermal fatigue and external corrosion. Internally, a high-efficiency ceramic honeycomb substrate provides maximum precious metal surface contact for optimal reduction of carbon monoxide, unburnt hydrocarbons, and nitrogen oxides. Precision-machined, thick OE-spec flanges ensure a leak-free seal without warping under torque, eliminating the exhaust leaks common to fatigued factory manifolds.
