An exhaust treatment device for an internal combustion engine includes a generally cylindrical substrate and sealing system which are swaged in place within a one-piece housing. The one-piece housing includes segmented inlet and outlet gas shields and diffusers which are spun from a single piece of tubing which also contains the substrate. The spun inlet and outlet gas shields and diffusers have segmented configurations including multiple concave and convex sections produced by spin-forming of the housing. The exhaust treatment device is assembled without the need for welding or any other high temperature operation.
