Some pictures of my Hooker LS swap manifolds. As you can see they are very well made and fit my Cutlass perfectly. These are the ceramic silver coated version, as you can see they are rusting from under the coating. Two years old and never run, never gotten wet or exposed to the elements. I found out Hooker has a 90 day warranty on the coating. These are the original type with 2 1/4" outlets. Now you also get 2 1/2" Seems like they would have made them 3 inch to start like Speedway did on their stainless steel cast LS manifolds.
If you need manifolds these work but skip the coating.

 

Holley started the 2-1/4" as that's what GM manifolds have, and these are modeled after the late F-body. The 2-1/2" ones followed due to demand. Speedway's manifolds came out long after Holley's did, and they then came out with the 3". There is FAR more demand for the 2 smaller sizes than 3", as most 3" systems use tube headers.
