The typical installed price to replace a catalytic converter on a 2008 Honda Odyssey ranges roughly from $750 to $2,500, depending on whether one or two converters are involved, and whether you choose OEM or aftermarket parts.
To understand this figure, it helps to know how many catalysts the Odyssey uses, what replacement options are available, and how labor costs vary by location and shop. The 2008 Odyssey commonly uses two catalytic converters in its exhaust system, and the total cost can change significantly based on parts choice, access to the units, and regional labor rates.
Cost factors and price ranges
These are the key elements that drive the overall price of replacing catalytic converters on a 2008 Honda Odyssey. The amount you pay will largely depend on how many converters must be replaced, and whether you opt for OEM or aftermarket parts.
- Parts costs: OEM Honda converters are typically more expensive than aftermarket direct-fit units. A single OEM converter can range from about $500 to $1,200, depending on whether it is upstream or downstream and where you buy it. Aftermarket direct-fit converters generally run from around $150 to $800 per unit.
- Labor costs: Installation time varies by vehicle access and shop, but a reasonable estimate is 1 to 3 hours per converter, with labor rates commonly ranging from $80 to $150 per hour. This can translate to roughly $80–$450 per converter for labor.
- Number of converters: The 2008 Odyssey often uses two catalysts; replacing both increases parts and labor costs compared with replacing a single unit. Some repairs involve components that are integrated with the exhaust manifold, which can add complexity and time.
- Additional costs: Gaskets, oxygen sensors, mounting hardware, and emissions-related checks can add $20 to $150 on top of the core price.
- Location and emissions rules: If you live in a state that requires CARB-compliant parts, you may need specific converters that meet local emissions standards, which can affect both availability and price.
In practice, total installed costs will reflect the combination of these factors. It’s common to see a two-catalytic-converter job land in the $1,200 to $2,500 range when OEM parts are used and labor is average to high, while aftermarket parts can push the total lower, often in the $750 to $1,800 range.
Replacement options
Here are the typical routes people take when replacing catalytic converters on a 2008 Honda Odyssey, with considerations for cost, fit, and reliability.
OEM vs aftermarket
OEM (original equipment manufacturer) parts are made to the exact spec of the parts that came on your vehicle. They tend to be more expensive but offer a guaranteed fit and original performance characteristics. Aftermarket direct-fit converters are generally cheaper and can still provide reliable performance, but quality varies by brand. If you live in a state with strict emissions rules, ensure any aftermarket part is CARB-compliant where required.
Remanufactured or salvage
Remanufactured or salvaged converters can be a lower-cost option, but they carry higher risk of uneven performance or shorter remaining life. If you choose this route, prioritize reputable suppliers who provide warranties and ensure the unit meets your state’s emission requirements and the vehicle’s specifications.
Before deciding, you should obtain multiple, itemized quotes that clearly separate parts and labor, and confirm whether the shop will inspect the rest of the exhaust system and sensors for a complete, reliable fix.
What to do next
To move forward, contact several local shops for up-to-date quotes tailored to your vehicle’s exact configuration (including whether both catalysts are needed). Ask for itemized estimates that specify parts type (OEM vs aftermarket), whether one or both converters are replaced, and any accompanying tests or warranty terms.
Summary
Replacing catalytic converters on a 2008 Honda Odyssey typically costs between roughly $750 and $2,500 installed, depending on the number of converters replaced, the choice of OEM versus aftermarket parts, and labor rates. Expect higher costs if both converters are needed or if OEM parts are used; lower costs with aftermarket or remanufactured options. Always obtain multiple quotes, verify emissions compliance where required, and consider the overall reliability and warranty when selecting parts and a shop.
