Hello, my readers! Welcome to today’s topic: Davico vs. Walker catalytic converters! As I am a vehicle enthusiast, I love to discuss different things regarding the parts and performance of the vehicle. And obviously, catalytic converters are essential components for any car.

These converters with magical filters reduce harmful engine emissions. In terms of brand, both Davico and Walker are recommendable for best performance. They each have their tricks and superb ideas to make the air cleaner. But what sets these brands apart? How do their products compare performance, construction, and pricing?

Wait! I am giving these answers in full detail. But you need to read the comparison guide about Davico and Walker catalytic converters. Hopefully, you will choose the better one between these two brands.

A brief to Davico & Walker Catalytic Converters:

Any exhaust system of a vehicle has this component. And guess what – its main task is to convert toxic gases that appear in the combustion process. These gases include hydrocarbons, carbon monoxide, and nitrogen oxides. But with the best catalytic converters, you can get fresh air with low or no harmful substances.

Davico was established in 1987 in Massachusetts (1, 2). Alternatively, Walker was founded in 1888 in Wisconsin (3). Both brands (Davico & Walker) are famous for their converters. Hence, converting toxic air to less harmful air is almost the same. These converters also meet EPA and CARB requirements.

Davico’s products are known for their efficiency and optimization (4). On the other hand, Walker’s converters have OE engineering and manufacturing expertise behind producing them (5).

Okay, let’s move to the next part to learn more about the differences between these catalytic converters.

Now, I want to share info about Davico catalytic converters’ features and benefits in detail:

High-Quality Materials

Davico prefers high-quality, durable materials to produce their converters (6). These materials include stainless steel and precious metals like platinum, palladium, and rhodium (7). However, rust and corrosion stay away from these materials long. That’s why you can get a long-lasting performance.

Efficient Emission Reduction

Davico catalytic converters can efficiently reduce harmful emissions like CO, NO2, and hydrocarbons (CnH2n+2). With reduced emissions, Davico converters enhance air quality. Also, they meet strict emission standards.

Direct-Fit Design

Mainly you can get direct-fit cat converters from Davico. But if you visit their website, you can find its multiple versions (8). These are CARB-compliant, dealer alternative, split-pipe, OBD II universal, and close coupled. Consequently, these converters fit specific vehicle makes and models. You can easily install them without any modifications or welding.

OEM Compatibility

Davico catalytic converters are compatible with original equipment manufacturer (OEM) specifications. You can use them as a direct replacement for the original one without voiding performance or warranty. Moreover, these converters are generally considered better for resale value and longevity (9).


As Davico catalytic converters work like OEM models, they will last long like the original ones. But here’s a thing you should know: “… no moving parts in a catalytic converter … used in the wash coat do not get consumed or used up” (10). So, there is less chance of replacing the converters though the company suggests doing it after 25000 miles.

Improved Fuel Efficiency

The low exhaust backpressure of Davico converters reduces engine stress. So they can provide you with better fuel efficiency and overall engine performance.

Compliance with Regulations

Davico converters meet or exceed federal and state emission standards. It ensures compliance with environmental regulations.


Davico offers a limited warranty on its catalytic converters. This manufacturer has set some conditions which you need to maintain to use a warranty. Typically, you can avail yourself of a warranty for up to 2 years or 25000 miles. You can read the PDF (11) for more about this warranty. It is indeed an assurance that any defects or issues are addressed promptly.

Wide Range of Applications

Do you have multiple vehicles like cars, trucks, SUVs, and commercial vehicles? Don’t worry, as you can use Davico products in your car. So, I hope this is an easy way to find the correct catalytic converters.


Davico catalytic converters are competitively priced. For instance, direct-fit EPA catalytic converters cost around $185, and CARB-complaint models cost $532. Though the manufacturer does not sell directly, you can find these products on online stores like Amazon, Car Parts, etc.

After going through Walker’s official website, I have found two types of warranties for catalytic converters: emission and structural. For EPA-compliant converters, you will get a 25000 miles (or 40000 km) emission warranty (15). The structural warranty is five years or 50000 miles (80000 km). Alternatively, for CARB-compliant converters, you get five years or 50000 miles (80000 km) of both emission and structural warranty (16).


Like Davico, you will get a durable performance from Walker converters. The construction and design of these products keep them away from rust and corrosion. Even if you face any technical issues, you can get support from Walker.
