The 2019 Honda Pilot with the 3.5-liter V6 typically uses two catalytic converters—one for each bank of the engine—for its dual-exhaust setup. This is the standard configuration for most US-market Pilots from that year.
This article explains the usual arrangement, where the converters sit in the exhaust system, and what to check if you’re inspecting, replacing, or diagnosing issues with the exhaust and emissions controls.
Configuration and placement
Understanding the layout helps with diagnostics, repairs, and parts sourcing. The V6 is a dual-bank engine, and each bank generally has its own catalytic converter before the exhaust from the two banks merges downstream.
Key details
Common features you should know about the 2019 Pilot’s catalytic converters:
- Two catalytic converters total—one on each bank of the 3.5L V6 engine.
- Typically located along the exhaust pipes near the engine, with downstream piping connecting to a shared exhaust path toward the rear of the vehicle.
- Exact placement and count can vary by trim level or production date; always confirm with the vehicle’s service manual or VIN-based diagrams.
Bottom line: Expect two catalytic converters in the standard 2019 Pilot exhaust system.
Maintenance considerations
When replacing or inspecting, ensure you refer to the VIN, as some market-specific variants or aftermarket configurations might differ. Emissions components are tied to the engine management and may require dealer-level diagnostic tools for proper verification.
Summary
In short, a 2019 Honda Pilot with the 3.5L V6 typically includes two catalytic converters—one for each bank of the engine. This dual-cat arrangement is designed to optimize emissions reduction and align with federal and state requirements for that model year.
