Abstract
A weldless flanged catalytic converter includes a body having an exhaust inlet end and an outlet end, and a snorkel tube disposed at one or both the exhaust inlet and outlet ends. The snorkel tube has a first end extending from the converter body and a second, distal end having a weldless flange that is integrally formed from the snorkel tube. A movable flange is disposed about the snorkel tube prior to the formation of the weldless flange. A method for preparing the weldless flanged catalytic converter includes disposing a movable flange (configured with the required tapped holes or other connecting means) over the snorkel tube of the converter. A second, weldless flange is prepared by flanging out a portion of the catalytic converter snorkel tube using appropriate metal forming techniques. In use, the weldless flange is held between the movable flange on the snorkel tube and a connecting flange from, for example, the exhaust system. In an alternate embodiment, the weldless flange includes a drawn spherical structure (i.e., ball fitting).
