ABSTRACT:
A concentric, offset, or obliquely formed spun converter assembly includes an outer shell defining an internal cavity that receives a catalyst substrate. Inner cones are positioned within the internal cavity at each end of the outer shell. Each inner cone has a tapered body portion and a transversely extending shoulder portion that abuts an outer edge of the outer shell. The shoulder portions mechanically lock the inner cones to the outer shell.
