Is it dangerous to drive with exhaust leak?
Driving with an exhaust leak is potentially dangerous as the fumes contain carbon monoxide. An exhaust leak can decrease fuel efficiency, causing your engine to work harder, and you to fill up your gas tank more frequently. A third sign your exhaust may be leaking is if your gas pedal vibrates while you are driving.
What problems does an exhaust leak cause?
When your vehicle has an exhaust leak, your air-to-fuel ratio balance could be disrupted. Improper air-to-fuel ratio can cause the engine to run less efficiently, causing it to reduce overall engine efficiency. Smelling gas fumes inside your vehicle can be a sign of an exhaust leak.
Can a leaking exhaust manifold cause a catalytic converter to fail?
Another common problem related to catalytic converter failure is a leaking exhaust manifold. In order to prevent this from happening, and avoid some costly repairs, Park Muffler has put together a quick guide to leaky exhaust manifolds and catalytic converter failure.
Can a catalytic converter be repaired without replacing the ECM?
Exhaust leaks are common and can skew oxygen sensor readings without setting other DTCs. A careful search might reveal exhaust leaks that, when repaired, “restore” catalytic converter function, at least from the point of view of the ECM.
What happens when a catalytic converter goes bad?
If air can’t get out the rear of the vehicle, it can’t come in the front end, so the engine dies because no air is coming in to form the fuel/air mixture. Another common problem related to catalytic converter failure is a leaking exhaust manifold.
Where does an exhaust manifold leak in a car?
Many times, it is covered with a heat shield, but an exhaust manifold can leak in 3 areas – the mounting surface (gasket) where it joins the engine, the gasket where the downpipe, or catalytic converter attach, or the manifold itself can crack and cause a leak. Listen carefully near the top of the manifold.

How does a catalytic converter work in an engine?
The exhaust manifold is bolted to the engine. It collects the exhaust gases from the cylinders and funnels them into one output tube. A catalytic converter cleans the exhaust gases, in a way, by reducing harmful fumes exiting the engine.
What does a bad catalytic converter smell like?
A properly working catalytic converter will convert hydrogen sulfide into odorless sulfur dioxide. When failing, you may notice a sulfuric, rotten egg-like smell coming from the exhaust. Unburnt fuel left in the exhaust by the bad catalytic converter produces the odor, and may even cause dark exhaust smoke. 4.
