The new part numbers together cover more than 400 popular late-model applications.


The Walker Emissions Control product line now covers an additional 21 million passenger-vehicle repair opportunities as a result of Tenneco’s introduction of 103 new direct-fit catalytic converter, premium muffler/muffler assembly, pipe, resonator and hardware part numbers.


Among the new parts now available through Walker suppliers are 27 additional direct-fit Walker CalCat California Air Resources Board (CARB) compliant catalytic converters, 23 direct-fit Walker Ultra Environmental Protection Agency (EPA) compliant converters and 29 premium, stainless-steel Walker Quiet-Flow SS mufflers/muffler assemblies.

“It is our daily mission to help vehicle service providers expand their emissions control businesses by providing superior product quality and coverage for vehicles entering the aftermarket replacement cycle,” said John Perrin, executive director, product management, North America Aftermarket, Tenneco. “Whether the consumer owns an import or domestic model, needs a CARB- or EPA-compliant converter or prefers a stainless steel or conventional muffler, shops that rely on Walker are positioned to earn the business.”
