The Honda Pilot typically uses two catalytic converters: one close to the engine and a second downstream in the exhaust path. This dual-cat setup is standard across generations and most markets.
Understanding the setup
To understand the question, it helps to know how emissions controls are arranged in the Pilot’s exhaust system. Most Pilots rely on a two-catalytic-converter configuration to meet stringent emissions standards while maintaining performance and fuel efficiency. While the exact routing can vary by market or trim, the two-cat arrangement remains the norm.
Generational breakdown
Below is a concise look at the exhaust setup for each generation of the Honda Pilot. The counts reflect the standard factory configuration and are typical for U.S.-market models.
- First generation (2003–2008): Two catalytic converters. A close-coupled cat near the engine and a second cat downstream in the exhaust path.
- Second generation (2009–2015): Two catalytic converters. The dual-cat layout remains consistent with improved emissions controls.
- Third generation (2016–2022): Two catalytic converters. The dual-cat setup is retained in the redesigned platform.
- Fourth generation (2023–present): Two catalytic converters. The dual-cat arrangement continues in the latest Pilot.
In short, across Honda Pilot generations, the standard configuration uses two catalytic converters: one near the engine and one downstream. There can be minor regional variations in routing, but the two-cat setup is the norm for most markets.
Maintenance considerations
Knowing there are typically two catalysts helps when diagnosing exhaust issues, planning replacements, or checking for emissions-related service notices. Both converters contribute to emissions control, engine performance, and fuel economy.
Summary
Answer: Two catalytic converters. The Pilot has traditionally used a dual-cat exhaust system—one close to the engine and one downstream—across generations, with rare regional routing variations. For model-year specifics, consult the vehicle’s service manual or a qualified technician.
