How many catalytic converters does a Chevy Traverse have?
The Chevrolet Traverse typically has two catalytic converters in its exhaust system, especially on models with the 3.6L V6 and dual exhaust. This two-converter setup places one close to the engine and a second farther back toward the rear, a standard configuration for most U.S.-market Traverses. Variations can occur by year or region, so checking your specific vehicle is advised.
Common configurations and what to expect
Here are the typical configurations you will encounter in the United States on Traverse models with the 3.6L V6 and dual exhaust.
- Two catalytic converters are typically installed in the exhaust system.
- The front catalytic converter, also called the close-coupled cat, sits near the exhaust manifold to reduce emissions quickly after startup.
- The second catalytic converter is located further back along the exhaust path, upstream of the rear section (muffler/resonator).
Bottom line: for most US-market Traverses with dual exhaust, expect two catalytic converters.
Year and engine variations
Over the model years commonly sold in the United States, the two-catalytic-converter arrangement has been maintained for the V6-powered Traverse. Specific layouts can vary by engine code or market, but the standard configuration remains two cats.
- 2009–2017: 3.6L V6 with dual exhaust typically features two catalytic converters.
- 2018–2023: 3.6L LGX/V6 with dual exhaust continues to use two catalytic converters.
- 2024–present: Current generation with the latest 3.6L V6 configuration maintains two catalytic converters.
If you own a non-U.S. market Traverse or a unique trim, verify with the owner's manual or service documentation for your specific exhaust layout.
Identification and inspection
To verify the number on your particular vehicle, a quick under-car inspection can help, but ensure the vehicle is safely supported and cool before touching any components.
Where to look
- Inspect along the exhaust pipe from the engine toward the rear; you should see two metal catalytic converter canisters with heat shielding.
- The first converter is typically just downstream of the exhaust manifold (front cat).
- The second converter sits further back, upstream of the rear muffler or resonator.
Note: If you are unsure or performing maintenance, consult a dealership or qualified mechanic to confirm the exact layout for your VIN and region.
Summary
The Chevrolet Traverse commonly uses two catalytic converters in its exhaust system, particularly on V6 models with dual exhaust. While variations can occur by year or market, the two-cat arrangement remains the standard configuration for most current U.S.-market Traverses. For precise confirmation, check your vehicle's service manual or contact a dealer with your VIN.
