A combined catalytic converter and muffler is provided. A catalyst is securely mounted in a canister which in turn is mounted intermediate a pair of formed internal plates. The plates are further formed to define an array of tubes therebetween. The tubes comprise an inlet to the muffler and an outlet from the muffler and communicate with the inlet and outlet of the catalytic converter. Selected tubes may have perforations or other apertures through which exhaust gases may communicate. At least one external shell is mounted to the assembled internal plates. The external shell is formed to define a plurality of chambers which communicate with apertures in the internal plates.
