Dorman 674-773 Exhaust Manifold Kit - Includes Required Gaskets and Hardware Compatible with Select Chevrolet/GMC Models

The manifolds with and without the hole for the O2 sensor appear to be mixed up. This item isn't supposed to have the hole, but the item I received did have the hole. The replacement I ordered did not have the hole, so it all worked out in the end after a bit of wasted time. It comes with the manifold gasket, cat flange gasket, heat shield hardware, and the 3 nuts to the cat flange (NO STUDS). No hardware to mount to the cylinder head, but they rarely do. Fit and function are great, finish quality is on par with most cast iron parts. Durability to be determined.

This part is an exact fit for the OEM part I removed after my engine had an argument with one of the exhaust valves. Dorman did an excellent job reproducing the OEM fitment. The part seems to be more substantial in that it weighs quite a bit more than the original. I've never had an issue with a Dorman part and I don't anticipate one this time.

Helped out a SIL with this. It was a perfect fit on her '17 Equinox. I would have given 5 stars but he cat. ring gasket came dented up. I had to get one from a local auto parts store at freakin' $11.65 plus fuel to get me there and back. NOTE: check all your included parts before you start the job. Overall, I would buy agian.

Stated it would work on my vehicle. However this was the wrong part

I was not sure if i should get the aftermarket manifold or from GM. Glad i got the dorman. to be thicker in most areas, especially around where my old one cracked. highly recommend.

Perfect fit definitely worth the price really appreciate the great part

Ordered this product twice and both times no gaskets were included. They wouldn’t send the gaskets and just said I had to return the whole thing. Manifold seemed fine and fit as it should.

Mi carro es un GMC Terrain 2017 motor 2.4. Y le quedó muy bien. Lo recomiendo. Y excelente precio.

Part is perfectly fit.

It was great until everything was taken apart just for me to realize the gasket was dented. Thankfully part source had the gasket pretty cheap but it was super inconvenient considering I was in the middle of the job. Make sure you double check all the parts before you start the job 😅😅

Came on time. The ad said "all gaskets and hardware included". Came with gaskets for both ends, 3 bolts for heat shield and 3nuts for cat converter. Not any manifold nuts or studs. Still a good deal but should have these in picture and not use words like "all" in the description. Also the oring type gasket was slightly damaged and is leaking. I called supplier and thought they would send a replacement but it looks like they were expecting me to remove this one from my car and leave it inoperable while it is returned and new one sent out. I will purchase one on my own and change it when it comes in. Not a nice job to do let alone twice. Roughly 2hr. Not the first doorman product to not satisfy.
