In 1927, John Goerlich founded the Associated Parts (AP) and Goerlich companies to cater to both wholesale and aftermarket customers. In 1928, they introduced a universal muffler to the market and later made mufflers their signature product and the focus of ad campaigns and promotions due to greater business potential. AP has since expanded to offer a comprehensive range of exhaust and emissions products through its online catalog.
Goerlich's, the aftermarket business, was rebranded under the AP name in 2006. AP has been known by several names in its lifetime, including Associated Parts, AP Exhaust Technologies, and AP Emissions Technologies.
