Dorman Exhaust Manifold Customer Reviews

I liked the gaskets that came with the manifolds better than the auto part store gaskets. The studs that came with it were machined too small so while locking them in they went to far into the flange. Had to buy another set that was machined correctly. The manifold was made of good cast material does exactly what it was designed to do. Didn't take long for it to start rusting so paint it with high temp paint before installing.

I took my new manifold to Ford for installation because of time constraints on my part. The installation cost was 6.4 hours, so expensive but I had my truck back on the road for my work immediately (so in that manner money in the pocket). The purchase cost was a lot less than stock but if it is as good as advertised then I will never have to replace it again.

Dorman Exhaust Manifold Guides

Dorman Exhaust Manifold Review

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.
