Abstract
A method of manufacturing a subassembly for an exhaust treatment device includes providing a metal sheet including first and second apertures having respective first and second sizes, and a one-piece pipe including first and second linear portions having respective third and fourth sizes. The method further includes defining the first size based on a first difference between the first size and the third size being less than or equal to a predetermined value, and defining the second size based on manufacturing tolerances of the pipe to assure that the second linear portion will pass through the second aperture while the first linear portion passes through the first aperture. The method further includes fixing the first linear portion to the sheet, expanding the second linear portion from the fourth size to an enlarged size less than or equal to the predetermined value, and fixing the second linear portion to the sheet.
