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. Since then Walker continued to innovate while developing the first stainless and aluminized steel mufflers, crankcase devices which were the forerunners of today's catalytic converters followed by the first aftermarket converter 16 years later. Walker was also the first aftermarket manufacturer to launch a Limited Lifetime Warranty for the thousands of professional installers.

Spot-welded bushings are featured on Walker Pro-Fit mufflers for greater stability and support, proving durability and long service life.
