Well I have finally recieved my Kook Headers. They are 1 3/4 stepped to 1 7/8, stainless steel. There design is awesome! Keep in mind I have owned a set of Edelbrocks, SLP's, FLP's and now these. Kooks instructions state that you might have to raise the motor in order to slide these headers in place, that was not the case. They slid in like butter. Also for the AFR headed guys like myself, the plug access is fantastic. I got all the plugs in on the passanger side in several minutes. Before on my FLP's I had to remove the header, to change plugs! I cant believe how easy they are to install. Note: I have done numerous header installs. I will post some Pictures when I get home.

 

nice, notice any differance with them on?

 

have not driven the car yet. I still have to install my NX kit, and motor mounts and other stuff..

 

Where can I get these headers? I have a heads/cam(GM847)/sprayed car so I would like the steped headers.
