How Much Is a Semi-truck Catalytic Converter Worth?

Semi-truck owners know catalytic converters are vital in reducing emissions and keeping their vehicles running smoothly. However, if they fail, replacing them can be costly. This article will discuss the worth of semi-truck catalytic converters, which trucks have the most valuable ones, and how much they are worth for scrap.


How Much is a Semi-Truck Catalytic Converter Worth? 

The cost of a new catalytic converter ranges from $500 to $2,000, depending on the damage’s severity and the truck’s make and model. Custom converters may be necessary for older or less common truck models, making replacement even more expensive. In any case, repairing or replacing damaged converters is crucial for both vehicle performance and cost savings in the long run.

Trucks with the Most Valuable Catalytic Converters 

Catalytic converters contain precious metals like palladium, rhodium, and platinum, which are becoming increasingly valuable, making them a target for thieves. The 2017-2022 Ram 2500, 2003-2022 Ford F-250, and 2019-2022 Lamborghini Aventador is some of the vehicles with the most valuable converters, with prices ranging from $2,000 to over $3,000.

Diesel Catalytic Converters Worth the Most 

Factors such as the vehicle make and model, catalyst material, and converter size and design determine the price of diesel catalytic converters. High-end vehicles and those using expensive materials tend to be the most costly. However, specialty converters can also have high price tags.

Catalytic Converters with the Highest Scrap Price 

The scrap value of catalytic converters varies depending on the vehicle type and the amount of precious metals they contain. Exotic cars such as Lamborghinis are more valuable because they use more expensive metals. At the same time, popular vehicles such as the Toyota Land Cruiser and Prius also command high prices due to their popularity and the materials used in their converters. The average scrap value is between $300 and $1,500. Still, it can be higher or lower depending on the market value of the metals.

How Much Do Thieves Get for a Catalytic Converter? 

Thieves can get up to $700 per converter from scrap yards due to the platinum and palladium used in the catalyst. Catalytic converter theft is common among trucks and SUVs. Prevention measures such as parking in well-lit areas and installing security devices can help. Signs of theft include abnormal exhaust system noise and decreased fuel efficiency.


Semi-truck owners should be aware of the value of their catalytic converters and take steps to protect them from theft. Repairing or replacing damaged converters is essential for vehicle performance and cost savings. By being informed, owners can get the most out of their converters while preventing theft.
