I bought a pair of SLP headers with out air. How hard is it to delete the tubes the are on the car that hook up to the manifold?

 

Not too hard, just remove the smog pump, the little black box, and all the tubes and hoses running from it. and plug up the line to the cat. If you won't be needing the tubes later, then just get a dremel or something with a cut off wheel and cut all the tubes, then just remove the manifolds, because when I took mine off they were a pain, some stripped even with a line wrench and the others were almost rusted in there.
