Our emissions control engineering centers share expertise and capabilities helping us to provide the latest technologies to customers throughout the world. Walker products are backed by OE engineering and manufacturing expertise enabling us to deliver quality engine-to-tailpipe solutions to the aftermarket meeting today's needs while developing solutions to tomorrow's challenges.

Today, catalytic converters are one of the main parts of our vehicle's exhaust systems. Installed in all cars sold in the European Community countries, the use of a catalytic converter has been mandatory for petrol cars since 1993 and for diesel cars since 1997. Conscious about the environmental challenges, Walker makes sure to comply to the latest European legislation in term of emission standards, to reduce drastically the amount of NOx gases being released by the exhaust system of both light vehicles & commercial vehicles. In June 2017, Walker has become the first emissions control solutions manufacturer to offer an aftermarket catalytic converter designed to comply with the European Union’s Euro 6 emissions standard.
