U.S. Custom Manufacturing opened its doors in 1978 as a part of U.S. AutoForce after seeing an opportunity in the exhaust business. Three years after opening, U.S. Custom Manufacturing bought their second and third pipe bending machines to help increase production. Exhaust pipes were the main product to come from the pipe shop, but since opening in 1980, it has expanded its production to other materials such as furniture, lawn and garden equipment, frame components, and handles and rails.
