Carbon monoxide can come into your car if you are having exhaust issues. Carbon monoxide is odorless and very harmful. Exhaust leaks can affect and damage your engine. If you have a bad leak, it can create a burn through the piston in the engine which can result in failure.
Catalytic converters may can become dislodged which needs to be addressed. There isn't always a red flag or warning when the catalytic converter fails. Your car mechanic may tell you not to worry about the exhaust issue but it needs to be taken seriously.
