A catalytic device and method for forming a catalytic device are described. The devices and methods described can be used for emissions systems in heavy duty diesel engines. In particular, a method of spin forming a catalytic device generally includes disposing a mat about an outer surface of a catalyst substrate and inserting the catalyst substrate and mat inside a shell. The mat is between the shell and the catalyst substrate. The shell, catalyst substrate, and mat can be spin formed into at least a generally elliptical shape but generally other than a circle shape.
