It's for the air injection. Part of the smog pump system.

Re: Tube thing on manifold

Depends on if you need to pass emissions in your area.

I don't have to pass emissions. So i'll be fine just to cut the hose off and put the headers on?

Re: Tube thing on manifold

Shouldn't need to cut it. There should be a rubber hose that connects the metal manifold pipe to the pipe that runs behind the motor. Once the manifolds are unbolted should just pull off. (At least that's how mine was). I also removed the smog pump when I installed my headers.

Okay thanks, need to do anything special to get rid of the smog pump? Like other than just unbolt it? I don't have my truck at home at the moment to check

Just unbolt it, and remove the belt for it.
