Abstract

A method of assembling exhaust components comprising the steps of: (a) providing an exhaust plate or other exhaust component having a first side, a second side, and an embossment, the embossment defining an aperture and a void contiguous with the aperture; (b) providing an exhaust pipe or other mating exhaust component having an end portion having a leading end, the end portion sized to be received by the void; (c) inserting the end portion of the exhaust pipe into the void; and (d) bending a portion of the embossment over the leading end of the end portion to lock the exhaust plate to the exhaust pipe. Step (d) may include flaring the embossment and a leading portion of the end portion of the exhaust pipe. Step (d) may be performed by punching the embossment to deform the embossment and the leading portion of the end portion of the exhaust pipe. The punch may be aligned with the embossment and with a passage defined by the exhaust pipe and punching the embossment to bend the portion of the embossment over the leading end of the end portion and into the passage and desirably also to flare the embossment and the leading portion of the exhaust pipe. The method also may include the step of forming the embossment, the aperture and the void in the exhaust component with a tool prior to step (a).
