I have installed aftermarket headers and off-road H-pipe on my 89 GT. I removed the cluster of hoses at the rear of the smog pump. I then placed a pipe cap on the metal pipe near the rear of the passenger cylinder head. My question is (1) Do i need to plug the outlet of the smog pump until i can afford the pump-delete idler bracket? (2) Do i still need the air tube that runs down to the H-pipe or can i crimp the outlet on the H-pipe or just weld it to seal it?
