The catalytic converter is made of a metal housing and packing material designed to remove harmful pollutants from your exhaust gas. The front of the converter is secured to the exhaust manifold with two bolts, with a doughnut gasket between the joint. The back of the catalytic converter is attached to the exhaust pipe with two bolts, with a doughnut gasket between the joint. Due to the doughnut gaskets, a rattle in a catalytic converter can only be coming from the heat shroud bolted to the bottom of the housing.
