How much does it cost to replace a catalytic converter on a Chevy HHR?
Replacing the catalytic converter on a Chevy HHR generally runs about $900 to $2,000, depending on parts and labor. In some cases—especially when OEM parts are preferred or the job occurs at a dealership in a high-cost area—the price can climb toward $2,500 or more.
The Chevy HHR was produced from 2006 through 2011 and uses a catalytic converter as part of its exhaust system. Costs vary with engine type (2.2L vs 2.4L), the converter’s location, and whether you use aftermarket or OEM components, as well as local labor rates.
What drives the cost
These items typically determine the total you’ll be quoted for replacing a catalytic converter on a Chevy HHR.
Parts and labor
A breakdown of common costs for the component and installation.
- Aftermarket catalytic converter: typically $150–$600 for the part itself.
- OEM (GM) catalytic converter: typically $400–$1,200 or more for the part.
- Labor: roughly 1.5–3 hours at shop rates; commonly $80–$150 per hour, with dealers often at the higher end.
- Additional parts and services (gaskets, clamps, O2 sensor replacement if needed): $50–$300.
- Taxes, disposal fees, and potential shop charges.
In most cases, the total cost is the sum of the part price, labor, and any add-ons or fees.
OEM vs aftermarket considerations
Choosing between OEM and aftermarket affects price, warranty, and potential emissions compatibility.
- Aftermarket converters can save money but may have shorter warranties or varying quality.
- OEM GM converters tend to be more expensive but match exact specifications and often come with longer warranties.
- Some shops apply a core charge for the old converter, which is refunded when the core is returned.
- Dealerships vs independent shops: dealerships may have higher labor rates but can offer OEM parts and formal warranties.
Ultimately, your choice between OEM and aftermarket influences the final price and long-term reliability.
Other important factors that can affect the quote
Beyond the core components, several external elements can shift the final price.
- Engine type and model year (2.2L vs 2.4L) and the converter’s placement in the exhaust system.
- Regional labor rates and whether you use a dealership or an independent shop.
- Accessibility, rust, and exhaust system condition—these can lengthen labor time.
- State emissions rules and whether a diagnostic check or inspection is required after replacement.
- Warranty coverage on parts and labor, and whether a warranty is honored at your chosen shop.
To avoid surprises, obtain multiple quotes and ensure each estimate details parts, labor, and any applicable core charges or fees.
Tips to save money and get a fair price
Use these strategies to lower cost while ensuring a proper, compliant repair.
- Ask for a detailed, itemized estimate that separates parts, labor, diagnostics, and fees.
- Get quotes from both a dealer and an independent shop to compare parts and labor.
- Inquire about core charges and whether they are refundable upon returning the old converter.
- Look for written warranties on both parts and labor and check for any available discounts or coupons.
With careful comparison, you can balance upfront cost with long-term reliability and emissions compliance.
Summary
The typical cost to replace a catalytic converter on a Chevy HHR falls roughly in the $900–$2,000 range, though OEM parts and dealership labor in costly regions can push prices higher. The exact figure depends on the engine (2.2L or 2.4L), the converter’s location, part choice (OEM vs aftermarket), and local labor rates. Getting multiple, itemized quotes and understanding warranties will help you secure a fair price while keeping your vehicle compliant with emissions requirements.
