Two catalytic converters. The 2014 Honda Pilot's 3.5-liter V6 uses a dual-cat exhaust with one converter on each bank of the engine.
In practice, that means the vehicle's exhaust path includes two catalysts, a sensor setup to monitor emissions, and downstream components such as a resonator and muffler. This configuration is designed to meet emissions standards and support diagnostics under OBD-II rules.
Exhaust layout and converter count
The following describes the standard stock configuration for the 2014 Pilot with the 3.5L V6. A dual-cat arrangement means two separate catalytic converters are integrated into the exhaust stream, one on each bank of the engine.
- There are two catalytic converters in the stock exhaust system — one for each bank of the V6 engine.
- Each converter is monitored by sensors (typically two oxygen sensors per bank: one before the catalyst and one after) to ensure the system operates correctly.
- The exhaust path generally continues from the converters to a resonator and then a muffler, reducing noise downstream.
In short, Honda's dual-cat setup for the 2014 Pilot is standard for its engine family, balancing emissions performance with reliable diagnostics.
Maintenance and replacement considerations
Before considering a repair, it's helpful to understand how the dual converters impact service and cost. Issues can affect either converter or both, and the diagnostic approach often centers on sensor readings and exhaust flow.
- Common codes related to catalytic converters include P0420 and P0430, which indicate catalyst efficiency issues on bank 1 or bank 2, respectively.
- Replacement decisions depend on whether one converter fails or if both require replacement to restore proper emissions performance; labor can be significant due to dual units.
- Costs vary by region and shop, but plan for parts and labor for two converters plus sensors and clamps if both units need replacement.
Regular inspection of the exhaust system, including oxygen sensors and heat shields around the catalytic converters, helps maintain performance and avoid unexpected failures.
Summary
The 2014 Honda Pilot uses two catalytic converters, one on each bank of its 3.5L V6. This dual-cat arrangement, paired with sensor monitoring and downstream exhaust components, is the standard configuration to meet emissions standards and support ongoing maintenance and diagnostics.
