Manifold, perfect fit for an 08 Trailblazer but the gasket was bent and had creases. One corner of the gasket cracked off when attempting to straighten. I had to go to local part store and purchase a new gasket. I would give more stars but I did have to spend more money to compensate for the lack of quality control.

Be careful and make sure it fits. When I ordered this manifold, the site stated that it fits my 06 Envoy SLT. Only to realize latter my Envoy 02 sensor is in the manifold. The manifold I need is 674- 990, it has the 02 port. The site also states that it fits my Envoy SLT . A bit misleading to have the "This fits your" section showing the same fit for both part numbers. Hoping that it can be exchanged for the correct one.

I installed this manifold kit on a 2008 Saab 9-7x with a 4.2L L6 engine. Couldn't be happier with it. I also purchased the the Dorman bolt kit and I'm glad I did. The stud kit that pops up as something people purchase with it, isn't needed at all. I bought the stud kit just to be on the safe side thinking they might work to secure the manifold to the head in a few places. The stud kit only fits the manifold outlet flange and the manifold kit comes with the three studs it needs. I really like the gasket that came with it because all three layers are spot welded together. The OE one wasn't spot welded and would have been a pain to install.

Replaced the exhaust manifold in my 2009 Envoy, everything fit perfectly. Fairly easy to change out and now she is running a smooth and quiet. Only thing I was unhappy about was the fact that it didn't come with the bolts. Good thing I ordered spare ones.
