  • 1908

    In 1908, William A. Walker and his twin sons, Williard and Warren, acquired control and ran a 'Walker Operation'. Even then, it would be several years before the company would enter its present line of business.


  • 1912

    In 1912, Willard Walker began a new venture with John Dwight that he called 'tire savers'. In those days, people stored cars for the winter, and tire savers lifted the car off the ground removing weight from the fragile tires.


  • 1916

    In 1916, in order to support the new business, a new production facility was built in Racine, Wisconsin. In that same year, the name officially became Walker Manufacturing Company.


  • 1920

    The jack business flourished throughout the 1920's.


  • 1929

    In 1929, Walker acquired Ajax Auto Parts Company and became one of the country's leading jack producers.


  • 1932

    Mufflers, in those days, were little more than tin cans. They provided little real benefit to the driver or passengers. Walker saw an opportunity to design a better product.

    In 1932, Walker patented what would be the first in a long line of engineering innovations, the louvered tube. It was the louvered tube muffler that earned Walker its reputation as the industry leader.


  • 1941

    As the automobile evolved, the needs of the industry changed. Engines became more refined and standards increased.

    In 1941, Walker's pioneering efforts in the exhaust industry included the first stainless steel muffler.


  • 1953

    In 1953, Walker introduced the first aluminized steel muffler. Walker also added special sound control chambers called 'Individual Tuning' to its original equipment mufflers. Walker later introduced 'Precision Tuning' which took into account greater horsepowers, automatic transmissions and higher compressions.


  • 1962

    With more and more cars on the road, people became concerned with preserving clean air and limiting pollutants.

    In 1962, Walker introduced crankcase devices which were the forerunners of today's catalytic converters. Walker's early success working with the California Motor Vehicle Pollution Control Board enabled it to forge ahead with new research.


  • 1963

    Walker successfully designed a catalytic reactor system for use in cars.


  • 1964

    Walker introduced its first chambered pipe. It consisted of a series of small tuning chambers spaced at select intervals along the length of the pipe from the manifold to the exhaust outlet.

    In 1987 Walker launched its now famous DynoMax Performance Exhaust product line that consists of a wide variety of direct-fit and universal stainless and aluminized mufflers, Cat-back systems, glasspacks and turbo mufflers and mandrel bent pipe which increases the flow and performance of the exhaust system.


  • 1988

    In 1988, Walker launched its new premium muffler call The Walker Advantage, with Absorbite. The Absorbite acted as a drying agent inside the muffler.

Walker was the first aftermarket manufacturer to launch a Limited Lifetime Warranty for the thousands of professional installers.


  • 1993

    In the 1990's, Tenneco, Inc. purchased two converter companies called Products for Power (PFP) and Perfection.

  • 1997

    1997, Walker again showed why it is the technology leader in the aftermarket industry by launching its famous Quiet-Flow premium muffler. In addition to the Limited Lifetime Warranty on this premium muffler, Walker is so confident that the consumer will be satisfied with their purchase, it offered further incentive called the Safe & Sound Guarantee. This guarantee allows the consumer to return their Walker purchase in 90 days if they are not 100% satisfied.
