Summary:A low profile catalytic converter for use with an internal combustion engine that has a canister provided with a plurality of smooth foil sections arranged in substantially perpendicular relationship with the top and bottom walls of the canister. The smooth foil sections are spaced from each other so as to form a plurality of substantially rectangular passages providing axially extending flow paths for the exhaust gas emanating from the engine. At least one corrugated foil strip is located in each of the passages and an arm is formed with each of the smooth foil sections that is secured together with a portion of the corrugated foil strip by separate welds to the top and bottom walls of the canister.
