Catalytic Converter for Honda Odyssey (2005-2007) 3.5L Bank 1 & Bank 2 & Rear

Direct-Fit Replacement Catalytic Converter Set for 2005-2007 Honda Odyssey (RL3)

What it Does: The complete catalytic converter set replaces worn factory exhaust manifolds and underfloor converters on the 2005-2007 Honda Odyssey to clear catalytic threshold trouble codes and restore factory exhaust velocity.

The Stock Honda Odyssey Substrate Breakdown

Factory catalytic converters on the third-generation RL3 chassis face rigorous thermal cycling from the transverse-mounted 3.5L J35 V6. Over extended mileage, elevated exhaust gas temperatures degrade the internal washcoat, resulting in ceramic monolith erosion, internal substrate sintering, and compromised exhaust flow. This deterioration routinely triggers persistent P0420 and P0430 diagnostic trouble codes, skews downstream O2 sensor feedback loops, and increases exhaust backpressure.

The Engineering Solution

Engineered as a comprehensive replacement for Bank 1, Bank 2, and the rear underfloor sections, this direct-replacement assembly features heavy-gauge stainless steel tubing and robotic seam welds to withstand thermal shock. Inside, high-efficiency ceramic honeycomb monoliths ensure uniform precious-metal washcoat dispersion for thorough hydrocarbon reduction without introducing flow restrictions. Precision-machined, OE-spec connection flanges eliminate exhaust leaks, bolt directly to existing downpipes and cylinder heads, and accept factory sensors to restore proper backpressure scavenging.
