On a 2015 Honda Accord, replacing the catalytic converter typically costs between $1,000 and $2,000 when using an OEM part, and about $500 to $1,200 with aftermarket parts installed. The exact price depends on engine type (2.4L four-cylinder vs. 3.5L V6), local labor rates, and whether any additional sensors or hardware must be replaced.
In this article, we examine how much you can expect to pay, what drives the price up or down, and how to get reliable quotes from shops in your area. We’ll break down the cost by part type, discuss regional differences, and offer tips to avoid surprises at the counter.
What determines the cost
Prices for catalytic converter replacement are shaped by several factors. The following list outlines the main drivers and how they typically affect the final bill.
- Part choice: OEM (dealer) catalytic converters are usually more expensive than aftermarket or direct-fit replacements.
- Labor rates and time: Shops bill by hour, and a typical replacement takes 1–3 hours depending on accessibility and sensor work.
- Engine variant and number of converters: The 2015 Accord comes with different setups (4‑cylinder vs. V6) and may have a single catalytic converter or multiple units in the exhaust stream.
- Additional components: O2 sensors, mounting hardware, gaskets, and heat shields may need replacement if damaged or contaminated.
- Vehicle condition and accessibility: Rusted bolts, corrosion, or tight spaces can extend labor time.
- Location and shop pricing: Regions with higher living costs or specialized emissions work can push prices upward.
In practice, these factors create a broad range, which is why you’ll commonly see quotes from roughly $500 to more than $2,000 for a full installed replacement, depending on the specifics above.
Cost scenarios by replacement option
OEM catalytic converter
When opting for an original equipment manufacturer part, expect higher material costs and a longer warranty. The following estimates reflect typical market ranges for a single catalytic converter on a 2015 Accord, installed by a professional shop.
- Parts cost: Approximately $800–$1,600 for a single cat, with higher prices for V6 models or dual-cat configurations.
- Labor cost: About $150–$350, depending on shop rates and the complexity of the job.
- Total installed price: Roughly $1,000–$2,000, before taxes and fees.
- Warranty: OEM parts often come with a manufacturer warranty that varies by part and dealership.
For most owners, OEM replacement prioritizes emissions compliance and long-term durability, but the higher price is a key consideration.
Aftermarket catalytic converter
Aftermarket or direct-fit catalysts provide a lower upfront price while aiming to meet emissions standards. The figures below reflect common quotes for aftermarket replacements on the same vehicle.
- Parts cost: About $300–$900, depending on brand and whether the converter is universal or direct-fit.
- Labor cost: Typically $150–$350, similar to OEM jobs.
- Total installed price: Roughly $450–$1,200, depending on local rates and whether sensors are replaced.
- Quality and emissions: Reputable aftermarket parts should pass emissions tests, but compatibility and fit can vary by model.
Aftermarket options can offer substantial savings, but it’s important to choose a converter that fits your Accord’s specifications and local emissions requirements.
Location-based considerations and practical tips
Prices can vary widely by region, shop, and the presence of any theft-related damage. The following tips help you navigate quotes and avoid surprises.
- Get multiple written estimates from independent shops and Honda dealers to compare parts and labor.
- Ask whether the quote includes or excludes taxes, disposal fees, and any required sensor replacements.
- Inquire about warranties on the part and labor, and what they cover (e.g., defect, installation issues).
- Ask if the quote assumes OEM or aftermarket parts and whether any core return fees apply.
By shopping around and asking precise questions, you can find a price that aligns with your preferences for durability, emissions compliance, and budget.
Summary
Replacing a catalytic converter on a 2015 Honda Accord typically runs from about $500 to $2,000, depending on whether you choose aftermarket or OEM parts, the engine variant, labor rates, and any additional sensor or hardware needs. OEM replacements tend to be pricier but may offer stronger emissions guarantees, while aftermarket options can save money if you choose reputable brands and ensure proper fit. Always obtain multiple written bids, confirm what’s included, and verify that the chosen part meets your local emissions standards.
