How many catalytic converters does a 2010 Honda Pilot have?

Two catalytic converters.

The 2010 Honda Pilot, equipped with a 3.5-liter V6, typically uses one catalytic converter on each bank of the engine, for a total of two. This dual-cat arrangement is common in Honda's V6 SUVs of that era and is designed to reduce emissions and optimize exhaust flow. The exact count can vary if the vehicle has undergone aftermarket modifications or regional variations, but the US-spec model generally follows this two-cat configuration.

How the setup works

In a V6 engine, there are two exhaust manifolds (one from each bank). Each bank feeds its own catalytic converter, which then merges into a common exhaust path before the muffler. This layout ensures efficient treatment of exhaust gases from all cylinders and supports regulatory compliance.

Locations of the converters

For the 2010 Pilot, the two catalysts are typically placed close to the engine on each bank, with pipes leading to the mid-pipe and then the rest of the exhaust system.

• One catalytic converter on the driver's side bank (left side) near the exhaust manifold


• One catalytic converter on the passenger's side bank (right side) near the exhaust manifold


• Each converter connects to downstream exhaust components (mid-pipe, resonator, and muffler) as the system progresses

These placements are typical for the 3.5L V6 Pilot; variations can occur with aftermarket exhaust work or rare regional specifications. If in doubt, consult the vehicle's service manual or inspect the exhaust system directly.

Variations by market or model year

In the United States, the 2010 Pilot with the 3.5L V6 generally uses two catalytic converters. Some markets or special editions could differ, but two units is the standard configuration for the model and year.

Summary

Bottom line: a 2010 Honda Pilot typically has two catalytic converters—one on each bank of the V6 engine—providing dual-stage emissions control. The layout aligns with Honda’s V6 exhaust designs, but always verify with a repair manual or by inspecting the vehicle if you’re planning maintenance or part replacements.

Can you unclog a catalytic converter instead of replacing it?

Unfortunately, cleaning your catalytic converter does not guarantee it will work effectively afterward. If your converter is defective, cleaning it will not make an impact, and any symptoms present before the cleaning process will return. In the end, if nothing works, a replacement is the way to go.
