Either your muffler or resonator has corroded and the the fiber is no longer held securely by mesh. The fiber has blocked your muffler and in addition to considerable power loss, you will experience high fuel consumption. If you attempt to drive fast by using a fair bit of throttle your engine will run hot.
exhaust manifold, exhaust pipe, catalytic converter, muffler, tailpipe, and hangers. Sometimes a resonator is included as well
Catalytic converter.
It could be transmission fluid or coolant, or a problem with the catalytic converter.
Vehicle burning oil? Might not show when converter is installed due to high temperature produced by converter (oil is burned and disipated in converter before getting to tailpipe).
It superheats exhaust gases and burns any unburned gases to clean up the emissions escaping from the tailpipe.
Sounds like a plugged catalytic converter. Or muffler resonator assembly. Either way, your exhaust is not getting out of your tailpipe at the rate it was designed to flow. You will ruin your exhaust valves driving it this way. Very expensive to repair, better get this fixed.
Could be the header pipe which usually contains a catalytic converter.
Catalytic converters clog due to the carbon that the car produces. Usually, when the carbon has built up inside the cat., black smoke will come out of the tailpipe when you rev the engine. In extreme cases, black soot is visible on the ground next to the vehicle's tailpipe. Crystal Woll
The catalytic converter is probably bad. It really isn't a big deal unless your car has to have emissions tests.
Typically, no, it cannot. If you have a clog in your exhaust 9 times out of 10 it is in the catalytic converter. The muffler can also collapse inside and cause clogs.
The smell of rotten egg is coming from your catalytic converter that is plugged up White smoke is an indication of water (usually antifreeze) in the exhaust.
