There are OBX headers and Y-pipe that are Federal Spec. I want from a fellow orger, if I'm Cali Spec. what are my issues going to be? Anything would help guys, I appreciate it.
I'm only aware of me having to cut away some cross member to make them fit...

That's all you have to do....

You're getting rid of all of your stock header/manifold/y-pipe components.

FWIW the tubes may be the longest but they're not long tube headers.

If you have an egr valve and are using 5.5 gen headers you will need to weld in a bung on the rear header, otherwise it'll bolt right up, I think the y pipe might be slightly different in length too, a friend of mine has these on his 4yth gen, i had them on my old 5.5, sound great but the flex section is low quality.....
