How much does it cost to replace a catalytic converter on a 2008 Chevy Malibu?

On a 2008 Chevy Malibu, a catalytic converter replacement typically runs about $350 to $1,500 in total, depending on parts and labor.


This article explains what drives that cost, the differences between OEM and aftermarket parts, how the engine choice (2.4L four-cylinder vs. 3.5L V6) can affect the price, and tips to save money while ensuring the repair passes emissions tests. It also covers scenarios where the issue may be related to sensors or exhaust leaks rather than the converter itself.


What drives the cost


Prices vary based on several factors; the following list highlights the main price drivers.



  • Number of catalytic converters in the exhaust layout (some Malibu configurations use one, others may use two).

  • OEM versus aftermarket parts (OEM parts tend to be more expensive but may offer a closer fit and warranty).

  • Engine type and corresponding exhaust layout (2.4L four-cylinder vs. 3.5L V6 can impact converter count and complexity).

  • Labor rates and shop location (urban areas and specialty shops typically charge more).

  • Whether additional components (oxygen sensors, gaskets, clamps) must be replaced during the repair.

  • Emissions requirements in your state or locality, which can influence the scope of the repair and compliance tests.


Understanding these factors helps set expectations about price ranges and variability by vehicle configuration and location.


Typical price ranges and how to read quotes


Prices combine parts and labor, and the following categories cover most quotes you’ll see.



  • Parts

    • Aftermarket direct-fit catalytic converters: roughly $120–$500

    • OEM catalytic converters: typically $350–$900, sometimes $600–$1,100 depending on model and supplier



  • Labor

    • Labor time: about 1–3 hours depending on access and exhaust layout

    • Labor rate: $75–$125 per hour is common; in higher-cost regions it can be $150–$200 per hour



  • Other potential costs

    • Gaskets, clamps, oxygen sensor replacement if needed, or minor exhaust-hanger repairs



  • Estimated total

    • Single converter with aftermarket parts: roughly $350–$900

    • Single converter with OEM parts: roughly $900–$1,500

    • Two converters (if applicable): roughly $700–$1,800 (aftermarket) or $1,400–$3,000+ (OEM)




Note: These ranges are general estimates and vary by location, supply chain conditions, and vehicle specifics.


Cost scenarios by engine/configuration


To help budget, here are rough ranges for common Malibu configurations. The 2008 lineup could involve one or two catalytic converters depending on engine and exhaust layout, which changes the price.



  1. One catalytic converter (typical for the 2.4L four-cylinder): aftermarket parts often $120–$500; OEM parts $350–$900. Labor usually 1–2 hours at $75–$120/hour; total roughly $350–$900 aftermarket, $900–$1,600 OEM.

  2. Two catalytic converters (possible on some V6 layouts): aftermarket parts about $250–$700 per converter; labor 2–4 hours; total roughly $700–$1,800 aftermarket or $1,400–$3,000+ OEM.

  3. Non-cat-related costs and inspections: if a related oxygen sensor or exhaust leak is found, expect added costs (usually $50–$250 per sensor plus labor).


When you receive quotes, ask if the price includes oxygen sensor work, mounting hardware, and a catalytic converter warranty. Some shops offer a warranty on the converter itself but not on labor or gaskets.


Tips to save money


Before seeking quotes, consider these practical steps to trim costs without compromising safety or emissions compliance.



  • Shop around and obtain at least 3 quotes, clearly specifying OEM vs aftermarket parts.

  • Ask about bundled pricing if you’re replacing other exhaust components or sensors at the same time.

  • Look for promotions or discounts from local shops and consider reputable independent shops for competitive pricing.

  • Confirm local emissions testing requirements and whether the repair will require re-testing after completion.


Being proactive with quotes, parts choices, and timing can help you secure a fair price while ensuring a proper, code-free fix.


Summary


Replacing a catalytic converter on a 2008 Chevy Malibu typically costs between roughly $350 and $1,500, depending on whether you use aftermarket or OEM parts, how many converters are involved, and local labor rates. Always factor in possible extra costs for sensors, gaskets, and potential exhaust work, and seek multiple quotes to lock in the best price while ensuring the repair passes emissions tests.
