The 2016 Honda Pilot typically has two catalytic converters — one for each bank of its V6 engine.
In the 3.5-liter V6 setup used in the 2016 Pilot, exhaust from both banks passes through its own catalytic converter as part of the emissions-control system. This dual-catalyst arrangement helps reduce pollutants more effectively and works with the vehicle’s oxygen sensors to monitor performance and compliance with emissions standards.
Exhaust layout and converters
The two catalytic converters are positioned along the exhaust path to treat exhaust from both sides of the V6 engine. The following breakdown highlights their general locations and roles.
- Front catalytic converter (front bank): located near the engine on the front-facing exhaust path; this is typically the first major converter the exhaust encounters after leaving the manifolds.
- Rear catalytic converter (rear bank): located downstream along the exhaust, farther back toward the midsection of the vehicle; this converter handles exhaust from the opposite bank and provides additional emission reduction.
In practice, this dual-converter arrangement supports robust emissions control for the Pilot's V6 engine and works in tandem with the vehicle’s sensors to monitor exhaust composition and performance.
Maintenance considerations
As with any modern vehicle, maintaining the exhaust system is important. Symptoms of Issues with catalytic converters can include reduced engine performance, unusual exhaust sounds, or a check-engine light. If you suspect a problem, a qualified mechanic can diagnose with a scan and visual inspection and advise on replacement or repair options.
Summary
The 2016 Honda Pilot uses two catalytic converters, one for each bank of its V6 engine. This dual-catalyst setup is designed to maximize emissions reduction and works with sensors to ensure the exhaust system meets regulatory standards. Regular inspection and timely maintenance help ensure continued performance and compliance.
