Spun-locked heads help resist ruptures due to backfires.
Bridge construction for structural strength and a long service life.
Durable internal partitions for greater interior structural stability and a long service life.
Strong, OE-style spot welds help improve structural stability and increase durability.
OE-style louvered tube technology lowers the engine emissions noise level for a premium, OE-style sound.
OE-style domed heads help reduce radiated noise.
A complete internal drainage system helps prevent condensate acids from collecting between partitions or at the muffler heads.
Internal tubes are mechanically joined to the partition to allow expansion and contraction during temperature changes.

This special design helps eliminate the breaking of spot welds and subsequent part distortion or loose part noise problems.

History

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.
