How much does it cost to replace a catalytic converter on a 2018 Honda Pilot?

The typical total cost ranges from about $1,000 to $2,000 for a single catalytic converter replacement with OEM parts, and roughly $600 to $1,400 with aftermarket parts. If both converters need replacement, expect about $2,000 to $4,500 or more, depending on part choice and local labor rates.

Replacing a catalytic converter on a 2018 Honda Pilot involves more than swapping a part. This article explains the main price drivers, provides realistic cost ranges for one or two converters, and offers practical tips to save while ensuring the repair meets emissions standards. The Pilot’s exhaust system uses catalytic converters to reduce pollutants, and failures can trigger a check-engine light or an emissions test failure. Costs include parts, labor, taxes, and any related repairs such as sensors or gaskets.

Cost overview

Prices can vary based on whether you replace one converter or both, and whether you choose OEM or aftermarket parts. Here is a general guide to what you can expect.

• One catalytic converter (OEM parts): roughly $1,050 to $2,200 total (parts + labor), depending on labor rate and shop.


• One catalytic converter (aftermarket parts): roughly $600 to $1,400 total, with labor.


• Two catalytic converters (OEM parts): roughly $2,000 to $4,500 total, depending on parts availability and labor time.


• Two catalytic converters (aftermarket parts): roughly $1,500 to $3,000 total, with labor.

Note: These ranges reflect typical quotes from independent shops and dealerships in the United States in 2024–2025. Actual prices vary by region, shop, and vehicle condition.

Cost drivers and considerations

Several factors influence the final price beyond the converter unit itself. Understanding these helps you plan and compare quotes.

• Part source: OEM vs aftermarket; OEM parts tend to cost more but are often preferred for fit and warranty.


• Labor rates: Urban or high-cost areas generally charge more per hour; some shops may have higher shop fees or diagnostic charges.


• Scope of work: Replacing a single converter versus both; some vehicles require extra exhaust piping, gaskets, or heat shields.


• Vehicle condition: Corrosion or seized fasteners can add time and labor to remove the old converter.


• Related repairs: Oxygen sensors, wiring, or mounting hardware may need replacement if they are damaged or affected by the failure.


• Emissions compliance: Some regions require specific emissions-certified parts; replacing with non-compliant parts can cause failure in tests.

Conclusion: Prices can swing based on location and the exact work required. Getting multiple written estimates helps ensure you’re paying a fair price for a proper fix.

Saving while staying compliant

These practical steps can help you reduce cost without compromising function or emissions compliance.

• Shop around: Request written quotes from at least three shops or dealerships to compare total costs.


• Ask about aftermarket options: In many cases, aftermarket catalytic converters are substantially cheaper and still meet emissions standards; verify with your state’s requirements.


• Inquire about bundled costs: Some shops offer fixed-price jobs that include parts, labor, and common components like gaskets and clamps.


• Consider timing: If you’re near an emissions inspection window, plan the replacement so the vehicle passes the test without a re-test.


• Verify warranty and legality: Ensure the replacement part and the repair comply with local emissions laws and vehicle warranty terms.

Bottom line: With careful shopping and by weighing OEM versus aftermarket options, you can find a price that fits your budget while keeping your 2018 Honda Pilot compliant with emissions standards.

What to ask when you get a quote

To avoid surprises, use this short checklist when comparing estimates:

• Is the price for a single converter or both?


• Are OEM or aftermarket parts included, and what are the warranty terms?


• What’s included in labor time (diagnostics, removal, reinstallation, sensors, gaskets)?


• Will they check for related issues (O2 sensors, exhaust leaks) that could add cost?

Getting clear answers up front helps ensure you’re comparing apples to apples and reduces the chance of unexpected charges at the end of the job.
