I don't rteally remember how it was all hooked up since I yanked mine some time ago, but I know on mine there wasn't any metal tube going to the EGR from the headers. On mine there was a tube that came off the stock headers that ran up to ports on the back of each head. From there it went to the two thermactor valves on the passenger side then on to the air pump. All the system does is pump air into your exhaust to thin it out for cleaner emissions. If you don't have emissions yank it. Changing plugs will be much easier.
