Noises
Many times a "clogged" catalytic converter is actually a broken one. Inside the unit, a honeycomb-like structure aids the converter in superheating the exhaust fumes, which cuts down significantly on emissions. Over time, this honeycomb structure can get brittle and crack or chunk off inside the unit, which will impede the flow of exhaust.This causes a highly erratic indolent and or stalling and petite or no potentiality on acceleration, further as higher engine temperatures. Provided your vehicle suddenly seems to lose extra than half its ability, the catalytic converter could be the culprit.
Bad Fuel Economy
Thanks to a clogged catalytic converter makes the engine profession all the more harder, Gauze milage can incision substantially. With that much pressure in the exhaust, it is like the difference between blowing out of a drinking straw or a 2-inch pipe. When the catalytic converter is clogged, the engine is trying to force all the exhaust out of a much smaller hole, in essence, which adversely affects the miles per gallon the vehicle will achieve.

For this reason, many times a clogged or broken catalytic converter will rattle or make vibrating noises when the engine is given gas. Sometimes a bad catalytic converter will rattle when shaken by hand--wait until the exhaust system cools to try this, because the converters get extremely hot.
