directions Those are for a 99, will be the same except you have no EGR to worry about.

Looks like that guy slid the headers in from the top.

I went in from the bottom.

No, but it makes reaching down there a lot easier if you unbolt them.

Yeah, headers with a catted Y pipe. Look at the air/fuel ratio.

Definatly go in from the bottom. Much easier. Cut the casting tabs with a saber saw, and it will make life easy. No unbolting the motor mounts or the starter. Just slides right up and in.
Good luck
