"The manifold and gasket fit correctly. The ring was not needed for this application. However the heat shield did fit and was not as good construction as the original. Ended up using the original heat shield. The car now runs very quiet and gas milage is back to where it is suppose to be the oxygen sensor was giving wrong readings because the old manifold was completely broken in half thus air getting to the sensor. Very pleased with the manifold." posted by: dc on October 23, 2014

"Brass nuts given to hook up manifold to exhaust will not stay tight. Keep your old ones and use them" posted by: BD on October 8, 2010

"With minimal modification (grinding) on the heat shield, the installation was very straight foward. I was dissapointed in receiving only one of two gaskets for the manifold to exhaust pipe, so I was forced to buy two locally which added another $9.00 to the overall price." posted by: on June 11, 2009 view all 5 reviews

A typical exhaust manifold is made of cast iron or tubular tubing steel. It is mounted to the exhaust side of the cylinder head and serves more than just one function. At the connection, an exhaust manifold gasket is used to ensure a good seal. Actually, the design for a particular exhaust manifold usually varies since it is attached to cylinder heads for efficiency in gathering the exhaust from each exhaust port. The number of the exhaust installed in a particular vehicle is dependent on the vehicle type. Those engine vehicles with cylinders arranged in-line normally have a single exhaust manifold while those with V-type cylinder arrangements usually have two separate exhaust manifolds, one mounted to each cylinder head. In your vehicle, the exhaust manifold serves as the network of passages that gathers the exhaust manifold from different ports and routes them toward the catalyst and mufflers in the exhaust system. One advantage of an exhaust manifold with free flowing passages of meticulously designed configuration is that it can enhance the vehicle's breathing. This type of exhaust manifold is called the header. Compared to the typical exhaust manifolds, the header is made up of separate equal-length tubes that further improve the flow of the exhaust gases. There are also headers that are capable of pulling the exhaust gases out of the cylinder heads, allowing the engine to perform better than the usual. Fortunately, exhaust manifolds in general do not require stiff maintenance since it is not that prone to damage.

In order to get rid of the harmful gases produced by your car's combustion engine, you need a top-quality exhaust manifold. It allows extremely hot exhaust gases to flow from the cylinder head to the exhaust piping. Over time, your car's exhaust manifold may get worn or damage. Replacing it immediately saves your vehicle from the possibility of overheating and stalling. To see which brand stands out among others, we've tested the Dorman exhaust manifold on our 2010 Ford Explorer. Here's what we have to say:

Dorman exhaust manifold features:

  • It's manufactured to match and even go beyond OE specifications.
  • It's 50-state legal; it passed the strict emission standards even in California.
  • It comes with all the parts needed for the installation.
  • It's constructed using cast iron for maximum durability and reliability.
  • It effectively seals the engine head and exhaust piping.
  • It's crafted under strict quality standards.
  • It comes in a naturally aspirated type.
  • It's manufactured especially for vehicles with an oxygen sensor in its exhaust pipe.
  • It's covered by a lifetime Dorman limited warranty.

We tried the Dorman exhaust manifold on our 2010 Ford Explorer and found these ups and downs:

The ups

  • It's easy to install due to its OE-compatibility; you just need a few simple tools and the installation can be done in less than 30 minutes.
  • The exhaust manifold's seals prevent fumes and noise, resulting in a quieter ride all throughout.
  • A longer service life can be expected thanks to the exhaust manifold's cast iron built.
  • It allows you to drive anywhere in the US because it's 50-state legal.
  • It's very affordable compared to other brands like Rugged Ridge and Omix.

The downs

  • Cast iron may still corrode over time so expect to see rust formation over time.
  • It has a dull finish but it's going to stay inside your vehicle, so it really doesn't affect the manifold's performance.

The conclusion

The Dorman exhaust manifold delivers remarkable performance, specifically in allowing extremely hot gases to flow from the cylinder to the piping. It's budget-friendly and it offers a long service life. With a lifetime Dorman warranty, rest assured that the company has got your back no matter what happens. What's more interesting is the fact that this part installs quickly and easily. So if you're on the lookout for a cheap yet reliable component, then we recommend the Dorman exhaust manifold.
