The catalytic converter comprises a metal honeycomb catalyst support which is anchored in a canister so that it cannot telescope or blow out. The honeycomb catalyst support is formed by folding a strip of metal back and forth upon itself. There are slots in the strip along the lines of folding. When the strip is folded to form the honeycomb, the slots become notches, the notches being aligned so as to define grooves on the periphery of the honeycomb. The canister has internal ridges that mate with the grooves on the honeycomb and anchor the honeycomb.
