The average cost for an exhaust manifold replacement is between $1,117 and $1,320.
Labor costs are estimated between $233 and $295 while parts are priced between $884 and $1025.

What are the symptoms of a bad exhaust manifold?
Symptoms of a Bad or Failing Exhaust Manifold Gasket
- Excessively noisy engine. One of the first symptoms of a problem with an exhaust manifold gasket is an excessively noisy engine.
- Decrease in power, acceleration, and fuel efficiency. Engine performance issues are another common symptom of a problem with an exhaust manifold gasket.
- Burning smell coming from the engine bay.
Can I drive with a bad intake manifold?
Generally a really bad intake manifold gasket will make a car run rough at idle and/or cause a service engine light to illuminate. As far as driving the car, as long as you don’t have a fluid leak or the car is not stalling or running rough, it should be fine to drive for a few months.
What happens when your intake manifold goes bad?
1. Engine misfires and decrease in power, acceleration, and fuel economy. A vacuum leak caused by a bad intake manifold gasket can throw off the engine’s air-fuel ratio and cause engine performance issues such as misfires, a decrease in power and acceleration, a reduction in fuel efficiency, and even stalling.
What causes a cracked manifold?
First, hot exhaust gases are now being vented under the hood, rather than being sent downstream through the exhaust pipe. If your exhaust manifold is cracked or leaking, the back pressure in the exhaust system will be incorrect, which can reduce engine power, cause sputtering and other problems.
Is a manifold leak expensive to fix?
The cost of the replacement gasket will vary depending on make, model and year of your car and how many cylinders the engine has. With the prices quoted above, you can expect a cost of $18 at the low end for do it yourself repairs to as high as almost $400 at a dealership to repair an exhaust manifold leak.
How do you tell if you have a cracked exhaust manifold?
If the manifold is cracked or has a leak, the back pressure in the exhaust system will be incorrect, which reduces engine power. Sputtering, sluggishness, and strange noises like ticking or clicking, and other problems are all symptoms of a compromised exhaust manifold.
What does a blown exhaust manifold sound like?
A cracked manifold will usually make unusual noises of some kind as some of the exhaust gasses are being forced out of the crack instead of out the exhaust. This may be more pronounced when the engine is cold and first started and can be anything from a clicking noise to a more pronounced whistling or whooshing noise.
What does a exhaust manifold leak sound like?
1. Excessively noisy engine. A faulty exhaust manifold gasket will produce an exhaust leak that will sound like a hissing or tapping sound coming from the engine. The sound may be especially pronounced during a cold start or during acceleration.
