How many catalytic converters are in a traverse?
In typical Chevrolet Traverse models with the 3.6L V6 and dual exhaust, there are two catalytic converters—one on each bank of the engine. This two-cat configuration is standard for most model years sold in the United States and many other markets.
The typical Traverse exhaust configuration
Catalytic converters reduce pollutants in the exhaust stream. For most US-market Traverse models equipped with the 3.6L V6, the exhaust system uses one converter per bank, resulting in two converters total. Each bank's converter is monitored by its own oxygen sensors as part of the vehicle's emissions control system.
Where to find them
In practice, you’ll find two converters along the undercarriage: one close to the engine on Bank 1 and a second on Bank 2 further back along the exhaust route. This dual-bank arrangement is standard for a V6 with dual exhaust.
The following breakdown highlights the two converters you should expect on a typical Traverse:
- Bank 1 catalytic converter (front bank tied to one side of the V6)
- Bank 2 catalytic converter (rear bank on the opposite side)
Both catalytic converters are part of the emissions system and can require replacement if clogged or damaged, or if the oxygen sensors indicate a failure.
Variations and maintenance notes
While two converters are standard for most Traverse models, especially in North America, always consult your vehicle’s service manual for the exact configuration on your year and market. Some exports or rare configurations may differ.
Summary
The Chevrolet Traverse generally uses two catalytic converters—one for each bank of the 3.6L V6 engine. This dual-cat setup is a common feature of modern GM SUVs, helping to meet emissions standards and optimize exhaust flow. If you’re diagnosing emissions symptoms, inspect both converters and related sensors.
