A concentric, offset, or obliquely formed spun converter assembly (10) includes an outer shell (12) defining an internal cavity (14) that receives a catalyst substrate (16). Inner cones (18,22) 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 (26,30) that abuts an outer edge (28,32) of the outer shell. The shoulder portions mechanically lock the inner cones to the outer shell. |
