Typically, replacing a catalytic converter on a 2014 Honda Accord costs around $900 to $1,500 for a single converter with aftermarket parts, and $1,500 to $3,000 or more if OEM parts are used or if two converters are involved. In California or other states with strict emissions rules, prices can be higher due to CARB requirements. Theft-related replacement or additional sensor work can also raise the bill.
Cost overview
Prices vary based on whether your Accord uses one or two catalytic converters, the type of parts you choose (aftermarket vs OEM), and local labor rates. The ranges below reflect common market prices in the United States within 2024–2026.
- Single catalytic converter (4‑cylinder 2014 Accord) — aftermarket parts: $200–$700; labor: $150–$300; estimated total: $350–$1,000.
- Single catalytic converter (4‑cylinder 2014 Accord) — OEM parts: $700–$1,200; labor: $150–$300; estimated total: $850–$1,500.
Note: Some 2014 Accords use two catalytic converters (front and rear). If two converters must be replaced, costs rise accordingly. The ranges below cover two-cat scenarios.
- Two catalytic converters — aftermarket parts: $400–$1,400; labor: $300–$900; estimated total: $700–$2,300.
- Two catalytic converters — OEM parts: $1,200–$2,400; labor: $300–$900; estimated total: $1,500–$3,300.
These figures are ballpark estimates intended to guide budgeting. Actual prices vary by region, shop, and the car’s exact configuration. Some shops bill by the hour (roughly $80–$150 per hour in many markets) and may add charges for gaskets, sensors, or other related work. In California, CARB-certified replacements can be required, which can push prices higher.
What affects the price the most
The main factors shaping the final bill include the number of catalytic converters, the choice of parts (OEM vs aftermarket), and regional labor rates. The following list outlines the typical drivers.
- Engine configuration and cat count (one vs two converters).
- Parts quality and source (OEM/brand-name vs budget aftermarket).
- Emissions compliance requirements (CARB status in California and some other states).
- Labor rates and shop location.
- Additional work tied to the repair (O2 sensors, coolant lines, gaskets, or exhaust piping).
To plan accurately, request written quotes from a few shops and specify whether you want OEM or CARB-certified aftermarket parts if you’re in a state with strict emissions rules.
What to expect at the shop
Most replacements follow a similar process: diagnosis to confirm the failure, removal of the old converter(s), installation of the new part(s), and a test run to verify proper operation and emissions readiness. Expect to wait a few hours for a single-cat job and longer for two-cat replacements. If bolts are rusted or sensors need replacement, it can add time and cost.
California-specific considerations
In California and some neighboring states, replacements often must be CARB-compliant. This can limit aftermarket options and influence price, quality, and warranty. Always ask for CARB EO-certified converters if you live in a CARB state.
Theft risk and related tips
Catalytic converter theft has been a concern in many areas. If theft is a factor, some shops may recommend upgrading to a more theft-resistant design or ensuring a proper warranty and documentation for future service.
Summary
For a 2014 Honda Accord, budget roughly $900–$1,500 for a single catalytic converter replacement with aftermarket parts, and $1,500–$3,000+ for OEM parts or a two-cat configuration. California CARB requirements can push prices higher, and regional labor rates will influence the final number. Always obtain multiple quotes, confirm CARB-compliance where required, and clarify whether the estimate covers sensors, gaskets, and warranty coverage.
