Dorman 674-940 Exhaust Manifold Kit - Includes Required Gaskets and Hardware Compatible with Select Chevrolet / GMC Models

Good product, works as expected. This was a no-problem part to install. It fit right on as expected and solved the problem caused by the wear and tear of the previous one. There has been no problem from the time of its installation up to the present. It's been good for the low price.

Identical to Oem and fits the same it's nice and solid with a powdercoat for add protection its casted and machined flawlessly.

Great price and delivery product fit just fine

Packaged well, comes with exhaust flange nuts and heat shield screw, manifold to cyl head and flange gasket. I read a lot of reviews that the replacement manifolds cracked after only a short time so I broke the manifold in gently, By that I mean, after installation I verified everything was right, and started the engine for about 1 minute and then shut down. I let it cool until it was cool to the touch, about 30 mins. I did this a few more times progressively going longer, and then went around the neighborhood gently driving it and came back and let it cool. Then it was ready for my wife to race, I mean drive it. Worked great. So far it's been a few months and no issue yet. The only problem I had was the crush gasket that goes on the outlet flange was damaged. It looked like the box had been dropped in shipping and the weight of the manifold dented the crush gasket. Luckily I saw that before I was ready to install and I had one on order for when I was ready. I'm sure they would have replaced it but I though for the few bucks it would be quicker to re-order vs do a warranty ticket. Still way cheaper than the local parts stores. So check all the contents before you are ready to install so you can either ask them to send you another or buy it.

For the price this worked just fine. I could have bought the Delco brand one for twice the price but with the miles on the motor it just didnt pay. How long it will last is anyones guess. It is working for now. I just hope this one doesnt crack like the last one did. At least not for a while.

Had a crack in the manifold causing my engine light to stay on. Also burning my O2 sensors in the manifold. I was a little hesitant to get because of the price. I received it had my mechanic install it. Everything aligned perfectly. Definitely a solid product. I suggest if you purchase this also get the O2 Sensor for as well. All in all great buy.

This manifold was used on my 2010 Chevrolet Equinox with a 2.4 cylinder engine. The quality appears to be as good or better as oem. It fit perfectly and the mounting points for the heat shields lined up as they should. The gasket was also a quality piece and wasn't that perforated material that does not last. 5 stars!

Didn’t come with a gasket.
