How much does it cost to replace a catalytic converter on a Lexus?
Costs typically range from roughly $1,000 to $3,000 for a single catalytic converter on most Lexus models.
The exact price depends on the model and year, whether you use an aftermarket or OEM part, labor rates in your area, and whether the vehicle has one catalytic converter or two. In some cases—such as high-cost urban areas, two-converter setups, or dealer-only parts—the bill can exceed $3,000.
What affects the price
Prices are driven by the vehicle’s configuration, part quality, labor costs, and any additional work required during replacement. The following factors have the biggest impact on the total:
- Model and number of converters: Some Lexus models have a single catalytic converter, while others (or certain trims) may require two or more units, which increases both parts and labor.
- Part type: OEM (dealer) parts tend to be more expensive than aftermarket or direct-fit alternatives, but may be preferred for fit, warranty, and emissions compliance.
- Labor rates and location: Urban, coastal, or dealer-heavy areas generally charge higher hourly rates and may have longer service times if access is tight.
- Additional components: Oxygen sensors, heat shields, exhaust manifolds, or seized bolts can add labor time and parts costs if replacement is needed.
- Theft risk and availability: In regions with higher catalytic converter theft, replacement costs can be affected by part availability and security measures at shops.
Prices can vary widely even within the same model year, so it’s wise to get multiple quotes and ask for a written estimate that itemizes parts and labor.
Typical price ranges (by scenario)
Prices below reflect common scenarios and are intended as a guide. Actual costs will depend on your specific Lexus model, location, and chosen parts.
- Single converter, aftermarket part, independent shop: Part roughly $100–$600; labor $150–$350; total roughly $300–$1,000.
- Single converter, OEM Lexus part, dealer or specialty shop: Part roughly $400–$1,800; labor $200–$500; total roughly $700–$2,300.
- Two converters on models with dual systems: Parts $800–$2,000+ per converter; labor $300–$800 total; total often $2,000–$4,500 or more.
Always verify inclusions in a quote (core charges, sensors, gaskets, and labor time) and ask about any additional diagnostics needed to confirm the failure isn’t caused by another component.
Warranty considerations
In the United States, catalytic converters are typically covered under the federal emissions warranty for up to 8 years or 80,000 miles, whichever comes first. Some states offer longer protections through their own programs. If your vehicle is still under warranty or under an extended emissions warranty, a portion or all of the replacement may be covered, potentially reducing out-of-pocket costs. Check with your Lexus dealer or warranty provider for specific terms applicable to your car and location.
Summary
Replacing a catalytic converter on a Lexus usually falls in the $1,000–$3,000 range for a single converter, with higher costs if OEM parts, two converters, or labor in expensive areas are involved. Prices depend on model, part type, and labor, and additional issues (like faulty oxygen sensors or rusted bolts) can raise the total. It’s prudent to obtain multiple, itemized quotes and to verify any applicable emissions warranty coverage before proceeding. If theft protection or local regulations influence pricing, factor those in as well. Always ensure the repair aligns with your vehicle’s warranty requirements and emissions compliance.
