Company History

A History of Meeting Exhaust & Emissions Market Demand

Since 1927

With its roots in the automotive replacement parts market, AP Emissions Technologies was founded in 1927 in Toledo, Ohio. From humble beginnings, AP transitioned into becoming one of North America’s largest aftermarket exhaust manufacturers and continued to grow becoming the leader in replacement exhaust and emissions parts over the many decades that followed.


John Goerlich acquires patent rights to the Taylor Loud Speaker muffler and founds the Associated Parts (traditional distribution channel) and Goerlich (retail distribution accounts) companies. AP’s roots reach back to the very beginnings of the automotive exhaust system business.

During World War II, AP/Goerlich produces quick-couple thin-wall steel pipe, known as “Victory Pipe” to transport fluids during the war. AP/Goerlich is awarded the Defense Department’s coveted “E” award.
