What Are CATs on a Pickup Truck?

CATs on a pickup truck are a popular modification that drivers can make to their vehicle. They are short for “catalytic converters,” and they are designed to reduce emissions.

In most cases, they are installed in the exhaust system of the truck, where they convert harmful gases from the engine into less harmful ones. The result is a cleaner-running vehicle that meets state and federal emission standards.

CATs on a pickup truck can be divided into two main types: universal and direct-fit. Universal CATs are designed to fit any type of exhaust system and are more affordable than direct-fit models.

However, direct-fit CATs provide better performance and efficiency due to their perfect fit for specific vehicles.

When selecting a CAT for your pickup truck, there are several factors to consider. You’ll need to take into account the size of the CAT, as well as its construction material (usually stainless steel) and design (usually elliptical).

Additionally, some models come with additional features such as oxygen sensors or temperature sensors.

Installing a CAT can be done either at home or by a professional mechanic. If you opt for the DIY route, make sure you have all the necessary tools and follow all instructions carefully to ensure proper installation. Additionally, it is important to use high-quality parts when installing your new CAT and check for any leaks before taking your vehicle out on the road.


CATs on a pickup truck can help reduce emissions while still providing good performance and efficiency. They come in two types: universal and direct-fit models, so it’s important to select one that fits your specific vehicle’s exhaust system properly. Also remember to use high-quality parts during installation and check for leaks before taking your vehicle out on the road.
