Walker manufactures direct replacement exhaust and emissions control parts, as well as some universally applicable ones, for classic and late-model cars and trucks. From the 1930s to 1950s, they were responsible for product improvements to exhaust pipes and mufflers that extended their life and reduced sound. But their largest technological leap forward happened in 1963 when they produced the first catalytic converter. As a Tenneco brand, Walker remains a leader in engine exhaust parts and emissions reduction components to this day.
