ABSTRACT:
There is disclosed a catalytic converter substrate of curved cross-sectional profile comprising a stack of modules individually formed of folded metal foil having contacting layers defining passages therebetween. The modules have a uniform thickness but various widths so as to conform the stack to the desired profile but with the combined thickness of the modules being made oversize such that the contacting layers are frictionally held together against relative sliding when the modules are compressively loaded by a retainer to completely conform to the desired profile.
