For Buick Enclave models, replacing a catalytic converter installed price typically ranges from about $600 to $2,000 per converter, with OEM parts on the higher end and aftermarket parts on the lower end. If both converters need replacement, the total cost can climb toward the upper end of that range.
The Enclave’s V6 powertrain commonly uses two catalytic converters, one upstream and one downstream. Prices vary by model year, whether the converter is CARB-compliant for California, the shop’s labor rates, and whether you buy OEM or aftermarket parts. Shopping around and getting multiple quotes is essential.
What affects the price
Several factors influence how much you’ll pay for a Buick Enclave catalytic converter, including the number of converters required, the part type, regional labor rates, and emissions requirements.
Parts price ranges
Below are typical price ranges you may encounter for Buick Enclave catalytic converters, depending on part type and compliance status.
- OEM direct-fit catalytic converter (GM/Delphi or equivalent): $500–$1,000 per converter
- OEM direct-fit catalytic converter (California CARB-compliant): $700–$1,200 per converter
- Aftermarket direct-fit catalytic converter (non-OEM): $150–$600 per converter
- Aftermarket universal catalytic converter (requires adaptation): $100–$350 per converter
Note: Many Enclave models use two catalytic converters (one on each bank of the V6). If both are needed, part costs typically double, though labor scales differently by shop and job complexity.
Labor costs and installation
Labor charges vary by shop, region, and vehicle condition, but the following ranges reflect common experiences for the Buick Enclave.
- Labor to replace a single converter: approximately 1–2 hours at $75–$150 per hour, total about $75–$300
- Labor to replace both converters: roughly 2–4 hours total, about $150–$600
- Additional costs to consider: diagnostic fees, O2 sensor replacement, gaskets, clamps, and mounting hardware
When budgeting, expect the total installed price to reflect both the parts chosen and the number of converters being replaced. OEM replacements will be at the higher end, while aftermarket parts offer lower upfront costs with varying fit and longevity.
Where to buy and how to save
To minimize surprises, gather quotes from multiple auto shops, verify whether the part is CARB-compliant if you’re in California or another emissions-restricted area, and ask about warranties on both parts and labor. Some customers save by opting for reputable aftermarket direct-fit converters rather than universal models, provided the installation shop confirms compatibility with their Enclave’s year and engine.
Summary
In practical terms, replacing a catalytic converter on a Buick Enclave typically costs between $600 and $2,000 per converter, depending on OEM versus aftermarket parts and whether one or both converters are replaced. Labor adds roughly another $75–$600 per converter, influenced by regional rates and shop policies. Always obtain written quotes for parts and labor from multiple shops and confirm CARB compliance if required in your area.
