  2. Decreased power, acceleration, and fuel efficiency.
  3. Burning smell from the engine bay.

What does a leaking exhaust manifold look like?

A leaking exhaust manifold will almost always create a ticking or tapping noise. Often, the sound is more pronounced upon startup when the engine and the manifold are both cold. The noise may diminish or disappear once the engine warms up and the manifold expands, closing off the leak.

What happens when exhaust manifold goes bad?

Decrease in power, acceleration, and fuel efficiency If the exhaust manifold gasket fails, the exhaust leak can result in engine performance issues such as a decrease in power, acceleration, and even fuel efficiency. The performance decrease may be minor at first, but will worsen over time if not addressed.

How much does it cost to replace exhaust manifolds?

The average cost for an Exhaust Manifold Replacement is between $994 and $1,087 but can vary from car to car.

What does a broken manifold sound like?

Can I drive my car with a bad exhaust manifold?

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.
