The Honda Pilot generally has two catalytic converters—one for each bank of the V6 engine. This arrangement is standard on most North American models across multiple generations, though specific configurations can vary by year or market. For exact counts on a given vehicle, consult the service manual or VIN-specific documentation.
What this means for the exhaust system
Catalytic converters are a key part of the Pilot’s emissions control. In a typical V6 setup with dual exhaust, each bank feeds into its own converter before the gases join and exit through the tailpipe. That means two units in most configurations rather than a single shared converter.
Where they are arranged in the Pilot
On most Honda Pilot generations, you’ll find one catalytic converter on the downpipe for each bank of the engine, usually located near the engine or under the front crossmember. A downstream converter sits further back in the exhaust path before the crossover to the rear exhaust.
Model-year variations
Regulatory requirements, market-specific design tweaks, and updates can lead to slight differences in exhaust layouts. While two converters is the standard, certain years or regional variants might differ. Always verify from official diagrams for your VIN.
By generation (concise overview)
Most Pilots across generations follow a two-converter layout, though niche regional specifications could alter the exact placement or add auxiliary emission devices upstream or downstream of the main cats.
- First generation (2003–2008): typically two catalytic converters, one for each bank, on a dual-exhaust setup.
- Second generation (2009–2015): commonly two catalytic converters, aligned with the dual-bank V6 layout.
- Third generation (2016–present): continues to use two catalytic converters in most trims, with potential variations for emission equipment in certain markets.
In practice, two catalytic converters cover the vast majority of Honda Pilot models; for your exact vehicle, consult the service manual or a VIN-based parts diagram.
Summary
Bottom line: most Honda Pilot models have two catalytic converters—one on each bank of the V6 engine. If you own a Pilot and need precise counts for repairs or replacements, check the official documentation for your exact year and market.
