How Much It Costs to Replace a Catalytic Converter on a Honda Pilot

Expect to pay roughly $900–$2,400 for a single catalytic converter replacement on a Honda Pilot in most U.S. states, or about $1,600–$3,500 in California and other CARB states. The final price depends on the model year, which converter is being replaced (manifold “pre-cat” vs. center/rear), OEM vs. aftermarket parts, and local labor rates. Many Pilots have multiple converters, so total costs can climb to $2,000–$6,000+ if more than one unit is replaced.

What Owners Typically Pay

The following breakdown summarizes common price scenarios for Honda Pilot catalytic converter replacement as of 2025. It factors in average shop labor rates ($120–$180/hour), typical parts pricing, and regional emissions rules.

• Non-CARB states, center/rear (underfloor) converter, quality aftermarket: $600–$1,400 total (parts $250–$700; labor $200–$450; plus gaskets/hardware/tax).
• Non-CARB states, manifold “pre-cat” (Bank 1 or Bank 2), quality aftermarket: $900–$1,900 total (parts $450–$1,000; labor $350–$800; plus incidentals).
• OEM parts (dealer-sourced), any state: add $500–$1,200 vs. aftermarket. Typical totals: $1,400–$2,600 (center) or $1,700–$3,200 (manifold).
• CARB states (e.g., CA, NY, CO): $1,600–$3,500 for a single converter due to CARB-certified parts and stricter compliance.
• Replacing multiple converters on the same visit (common on older Pilots): $2,000–$6,000+, depending on which units and parts chosen.
• Possible add-ons: oxygen sensors $100–$250 each, extra labor for rusted hardware, and wheel alignment if exhaust drop requires subframe loosened (rare).

These figures reflect typical retail pricing; dealer quotes trend higher, while independent shops may be lower. Complex rust or seized fasteners can push labor costs beyond the ranges shown.

Why the Price Varies

Several factors drive how much you’ll pay to replace a Honda Pilot’s catalytic converter. Understanding them helps you compare quotes more effectively.

• Which converter: Pilots commonly have two manifold (close-coupled) converters and one center/rear converter; manifold units are pricier and more labor-intensive.
• Emissions rules: CARB-compliant converters cost significantly more and must match an executive order (EO) number for your exact vehicle.
• Parts choice: OEM parts offer OE fit and longevity, but reputable aftermarket options can save hundreds if allowed in your state.
• Labor time: Underfloor cats often take 1.5–3.0 hours; manifold cats can run 3.0–6.0 hours, especially on rust-belt vehicles.
• Related components: New gaskets, hardware, and sometimes oxygen sensors are commonly recommended to ensure a proper seal and emissions performance.
• Theft or damage: Stolen cats often require extra pipe work, shields, or wiring repairs, increasing the bill.

When comparing estimates, make sure each quote clearly identifies the converter position, the part type (OEM vs. aftermarket, EPA vs. CARB), and all included incidentals.

Model-Year Notes for the Honda Pilot

Costs can differ slightly by generation because of packaging and parts availability. Here’s what to expect across common model years.

• 2003–2008 (1st gen): Typically three converters (two manifold, one underfloor). Manifold replacements are the most expensive; underfloor is comparatively cheaper.
• 2009–2015 (2nd gen): Similar three-converter setup; repair economics mirror the first generation. Rust can complicate removal on high-mileage vehicles.
• 2016–2022 (3rd gen): Still uses multiple converters; CARB compatibility and part availability can heavily influence price.
• 2023–2025 (4th gen): Newer models are less likely to need replacement unless stolen or damaged; OEM pricing remains high, and CARB rules still apply in applicable states.

Always confirm the exact converter count and position using your VIN, as emissions packages and fitments can vary by market and year.

Sample Line-Item Estimate

To help you benchmark quotes, here’s a typical independent-shop estimate for a single underfloor converter in a non-CARB state using quality aftermarket parts.

• Converter (EPA-compliant aftermarket): $450
• Gasket/hardware kit: $45
• Labor (2.0 hours @ $150/hr): $300
• Shop supplies and tax (varies by locality): $50–$90
• Estimated total: $845–$885

Switching to an OEM converter could raise the parts line by $400–$900; a CARB-certified unit could add $300–$1,200 vs. EPA-only parts.

Insurance, Warranties, and Ways to Save

These practical considerations can lower your out-of-pocket cost or prevent repeat failures.

• Insurance: Comprehensive coverage typically pays for theft-related catalytic converter replacements (minus your deductible).
• Emissions warranty: Federal coverage for emissions components is 8 years/80,000 miles on new vehicles; check if you’re within limits.
• Aftermarket vs. OEM: In non-CARB states, quality aftermarket units can be cost-effective; in CARB states, only approved parts will pass inspection.
• Prevent theft: Install a catalytic converter shield or cage ($200–$600 installed) and park in well-lit or secure areas.
• Address root causes: Misfires, oil burning, or coolant leaks can destroy a new converter; fix these first to avoid repeat costs.

Ask shops to itemize parts, labor hours, and certification (EPA/CARB). Confirm warranty terms for both parts and labor before authorizing work.

How to Tell If Your Converter Needs Replacement

While a diagnostic scan is essential, these symptoms can indicate a failing or compromised catalytic converter.

• Check Engine Light with codes like P0420/P0430 (catalyst efficiency) or sensor-related faults after verifying sensors are good.
• Rattling from the exhaust (melted or broken substrate), sulfur/rotten-egg smell, or noticeable power loss at higher speeds.
• Failed emissions or smog test, especially in states with periodic inspections.

A qualified technician should verify with live data, exhaust backpressure tests, and inspection before recommending replacement.

Bottom Line

For most Honda Pilot owners, a single catalytic converter replacement runs about $900–$2,400 in non-CARB states and $1,600–$3,500 in CARB states, with higher totals when multiple units are involved or when OEM parts are used. Get multiple itemized quotes, verify the correct part for your VIN and state, and fix any underlying engine issues to protect your investment.

Summary

A Honda Pilot catalytic converter replacement typically costs $900–$2,400 per unit in most states or $1,600–$3,500 in CARB regions, depending on which converter is replaced, parts choice, and labor time. Pilots often have more than one converter, so the overall bill can exceed $2,000–$6,000 if multiple units are replaced. Confirm parts certification for your state, compare itemized quotes, and address root engine problems to prevent repeat failures.

Why are Honda Catalytic Converters so expensive?

• Valuable Metals: Catalytic converters contain precious metals like platinum, palladium, and rhodium.
• High Demand: Older vehicles, including models like the Honda Accord, often have catalytic converters that are easier to remove and contain higher amounts of these precious metals compared to newer vehicles.

How much will a mechanic charge to replace a catalytic converter?

For direct-fit options, a replacement can cost anywhere from $300.00 to $2,500.00, depending on the model, for just the cost of the part. You should also think about labor costs, which could cost between $70 and $130 an hour to install the converter.

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

Labor costs are estimated between $291 and $427 while parts are priced between $1,688 and $1,788.

Is it worth it to replace my catalytic converter?

It’s worth replacing a catalytic converter in the financial sense. Not having one can do costly damage to your engine and exhaust system as well as significantly lower your gas mileage. It may also be difficult to sell your vehicle or get a reasonable price for it without one.
