what i did was crank it up and start pulling vac hoses and plugging them...if you pull one and it dies,then put it back,and for the exaust stuff...take your heat shield off(youll have to cut and resplice the o2 sensor wire)get you 4 1/4 pipe plugs and put them in place of the 4 pipes on the manifold,and for the other two...cut them as close to where they hook up down low,pinch them with some vice grips and weld
