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.

An exhaust treatment device for a motor vehicle includes upper and lower shells which are welded together to form inlet and outlet sections and a treatment section which may be occupied by a monolithic catalytic converter element. Inlet and outlet stubs which conduct exhaust gas into and out of the exhaust treatment device are joined to the device by means of generally hemispherical sockets formed integrally in the upper and lower shells and mating with hollow spherical sections incorporated in the inlet and outlet stubs.
