The fit wad great. But issue had was ordered both sides. But when took to shop to have done. They called said had 2 driver sides. Had wrong part in box or box labeled wrong. So they had to order passenger side and cost me 2 times more. Had to send other one back. Was 2 more days no truck. So check the parts in box. Before scheduled repairs.

Used on a 2002 Yukon 2500 xl with 6.0. Fit was perfect included gaskets did not leak and were good quality. I did use the bolts that came with it and had no problems at all. All stamped numbers matched the original. I have ordered many Dorman products before and have never had any problem or complaint. Always good quality and longevity with a great price.

Good price and very fast delivery. Perfect fit for my 2001 Chevy 2500HD 6.0 litre. I needed one with an EGR port, which this one has, as well as another port for something else. Came with all gaskets needed and bolts to connect to the exhaust pipe. Highly recommended to replace the manifold to head bolts while you're at it.

Broken EGR bolts in the stock manifold lead to buying this replacement. It fit as expected, and works. You will need new manifold bolts.

Use for 2002 silverado 1500HD.With the Beefy/thick flange gasket that pushes into the lower exhaust pipe I could not easily tighten the bolts to the block since it was propt up.I used a thiner factory gasket for this seal and it works great ($30 CAD).It has an extra port blocked with a steel plate on the flange of the hole. I hope the steel plate stands the test of time.

Used for a 99 1500 5.3. Replaced because there was an exhaust leak. Sounds nice and works just like oem. This is for the passenger side and does not need the smaller o ring gasket as it is for the driver side. Would be nice if it came with the bolts.

replaced these on our Silverado. Our stock manifolds had an exhaust leak near the firewall. So I decided for the price of these, to just go ahead and replace the entire manifold. New and shiny. Looks good. One thing I did not like was that the replacement gasket this kit comes with did not have the holes required for the change. I had to punch new holes which for me was not an easy task. Other than that. great product.
