The typical total cost to replace a catalytic converter on a Honda is about $1,000 to $2,500, with OEM parts generally being more expensive and aftermarket options offering savings. Labor usually accounts for a portion of the bill and can range from roughly $75 to $450 depending on the shop and location.
Costs vary by the exact Honda model and year, whether the vehicle needs the front pre-cat or the main catalytic converter, part availability, and regional labor rates. In some cases, additional components such as oxygen sensors or exhaust gaskets may be needed, which adds to the price. Theft-related replacements and scenarios involving multiple failed sensors can push the total higher.
Cost factors that influence the price
The following breakdown highlights the main drivers behind the total bill for a Honda catalytic converter replacement.
- Parts costs: Direct-fit aftermarket catalytic converters for Honda models typically range from about $300 to $900. Genuine Honda (OEM) parts are usually higher, commonly $600 to $1,800 or more depending on model and whether it’s the pre-cat or main cat.
- Labor: Expect about 1 to 3 hours of shop time. With typical labor rates of roughly $75 to $150 per hour, labor could be roughly $75 to $450.
- Additional components and services: You may need new gaskets, clamps, or an oxygen sensor, which can add $20 to $150 for parts and a similar amount in labor if replacement is required.
- Tax, disposal, and shop fees: Local taxes, environmental disposal fees, and occasional diagnostic or processing charges can affect the final price.
In practice, these factors combine to create a broad range. To avoid surprises, get multiple written estimates that itemize parts, labor, and any ancillary fees, and confirm whether the quote uses OEM or aftermarket parts. In many cases, opting for a reputable aftermarket catalytic converter can provide substantial savings without compromising reliability.
Summary
For most Honda models, a catalytic converter replacement typically costs between $1,000 and $2,500 in total. OEM parts tend to push toward the higher end, while aftermarket options can reduce the cost. Labor and any additional parts (sensors, gaskets) influence the total, and prices vary by model, year, and location. Always obtain several quotes to compare and ensure clear inclusions before proceeding.
