Default Hooker Super Comp fitment...

It looks like the crossover pipe ports are not exactly in the same location on the Hookers as in the OEM exhaust manifolds.

Anybody ever installed these?


On the OEM's, the port is centered over the 4,6 ports, but on the Hookers, neither side is centered?

Not knowing what year your car is, the left should not be an issue. On the right side, you can bend the EGR pipe to make it fit or if you follow the directions supplied with the headers, it says to cut a section of the pipe out and weld it back together. It's been awhile, the instructions should be on Hooker's site.

I ran those on my 94 for a few years. On the right side you can disconnect the air tube bracket from the rear of the head, and push the tube toward the firewall to make it fit. No cutting required. Also, not having a solid flange for the tubes to connect can cause a real PITA to get all of the header bolts aligned and tight.
