In most Hondas, replacing a catalytic converter installed costs roughly $900 to $2,500, depending on model and parts choice. The price hinges on OEM versus aftermarket parts, how many converters the car has, and local labor rates. Theft or California CARB requirements can push costs higher.
The question involves several variables: the specific Honda model and engine, whether you need a single cat or multiple cats, the type of part you choose, where you live, and current market conditions for exhaust components. This article lays out typical costs, factors that influence price, and ways to save.
Cost drivers
Before the following list, here are the main elements that determine how much you’ll pay for a catalytic converter on a Honda.
- Vehicle model and engine configuration: Some Hondas use a single catalytic converter, while others (particularly certain V6 or hybrid setups) may have two or more. More converters generally mean higher parts and labor costs.
- Parts vs. labor mix: OEM (dealer) converters tend to be pricier than reputable aftermarket options. Labor costs vary by shop and region and can be a sizable portion of the total.
- Emissions rules and location: CARB-compliant converters in California and certain other states can be more expensive due to stricter specifications and limited aftermarket availability.
- Warranty status and vehicle age: If the vehicle is covered by emissions warranties (often 8 years/80,000 miles federally, with longer terms in some states), a portion or all of the replacement may be covered.
- Theft risk and related damage: In areas with higher catalytic converter theft, there may be additional costs for mounting hardware, sensors, or repairing related exhaust components.
These factors together shape the final price you’ll receive in a quote.
Typical price ranges for common Honda setups
These ballpark installed-cost ranges reflect typical U.S. prices as of 2024–2025. Actual quotes will vary by model, part choice, and location. The numbers below assume a single catalytic converter; multiple-converter setups cost more.
- Single catalytic converter (most Civics, Accords, CR-Vs with one cat): aftermarket replacement installed ≈ $800–$1,400; OEM replacement installed ≈ $1,200–$2,500. In CARB states or high-demand markets, the upper end may be higher.
- Two catalytic converters (less common on many models): installed ≈ $1,800–$4,000 or more, depending on part quality and labor.
- Theft-related replacement (cat stolen or severely damaged): installed ≈ $1,200–$2,800, depending on extent of damage and the number of parts replaced.
Prices in California or other states with strict emissions requirements can push costs higher due to CARB-compliance needs and limited aftermarket options.
Warranty and coverage considerations
Check whether your vehicle is still covered by emission-related warranties. In many cases, catalytic converters and related emissions components have an 8-year/80,000-mile federal warranty, with longer or additional protections in California for certain models. If a defect is the cause, coverage may reduce your out-of-pocket costs. Always verify coverage with your dealer using your VIN.
Ways to save money
Practical steps can help reduce the bill without compromising safety or emissions compliance.
- Shop around and get multiple quotes from reputable shops. Labor rates vary, and some shops may include diagnostics or disposal fees.
- Choose parts wisely: CARB-compliant aftermarket options can save money in many states; compare OEM versus brands with solid reputations for longevity.
- Verify warranty eligibility before paying: if the repair is covered, you’ll want to pursue dealership repair or an authorized service center.
- Diagnose the root cause: misfiring engines or failing oxygen sensors can damage a catalyst. Fixing these issues first can prevent repeated failures and may be cheaper in the long run.
- Avoid speculative “cat cleaning” unless recommended by a qualified technician. If the catalyst is physically damaged or clogged beyond cleaning, replacement is usually necessary.
- Maintain the vehicle to extend catalytic converter life: timely spark plug, oxygen sensor, and fuel system maintenance helps prevent cat damage.
Following these tips can help you balance cost with reliable, compliant operation for your Honda.
Summary
Replacing a catalytic converter on a Honda typically costs between about $900 and $2,500 installed, with the exact number driven by model, number of converters, part type (OEM vs aftermarket), and local labor rates. In CARB states or high-cost markets, expect higher prices. If your vehicle is still under emission warranty, coverage may reduce your out-of-pocket expense. Always obtain multiple quotes and confirm the root cause of the issue before proceeding with replacement. A careful approach can save money while keeping your Honda compliant with emissions standards.
