The 2008 Honda Pilot has two catalytic converters in its exhaust system — one for each bank of its V6 engine.
In this model, the 3.5-liter V6 uses a dual-bank exhaust arrangement, with a catalytic converter associated with each bank. This mirrors Honda’s approach on many V6 setups from that era, where emissions control is achieved by treating exhaust from both sides of the engine separately before it merges back into the rest of the system.
Catalytic converter layout in the 2008 Pilot
The following describes where the two converters are typically located within the exhaust path.
- Left bank (driver-side) catalytic converter, positioned close to the engine to begin emissions reduction early in the exhaust flow.
- Right bank (passenger-side) catalytic converter, similarly located near the engine on its respective side, handling exhaust from its bank.
These two converters work in tandem to reduce pollutants from both sides of the V6 engine before the exhaust proceeds through the rest of the exhaust system.
Maintenance and diagnostics
If you experience symptoms such as reduced performance, a check engine light, or abnormal exhaust sounds, a qualified technician should diagnose the issue using standard OBD-II codes and, if needed, direct measurements of catalytic efficiency and backpressure. In practice, issues may involve one or both converters depending on the fault, so a professional evaluation is essential for proper repair decisions.
Summary
In summary, a 2008 Honda Pilot has two catalytic converters—one for each bank of the V6 engine—placed along the exhaust path near the engine as part of the vehicle’s emissions control system.
