Going the Extra Mile for Your Business
From the jobsite to the delivery route, you rely on your vehicle to keep up with the demands of your business. Whether it’s a van delivering packages or a medium-duty truck hauling supplies to the construction site, you need all the systems of your vehicle, including the catalytic converter and muffler, operating at peak efficiency.
The exhaust system keeps the dangerous gases that are created during the combustion process from entering the cabin. In addition, it “cleans up” these gases that include carbon monoxide, nitrogen oxides and hydrocarbons before they enter the environment. Key parts of the exhaust system, the catalytic converter is vital for converting the harmful gases into H2O (water), CO2 (carbon dioxide) and N2 (nitrogen) while the muffler is designed to quiet the sound of the engine as the emissions pass through and out of the exhaust system.
Hardworking light commercial vehicles rely on mufflers and catalytic converters that are in top condition. Walker® mufflers and catalytic converters help keep your light commercial vehicle – or your entire fleet – on the road. Find parts for your light commercial vehicle.
