if you have cats and mufflers you should be able to pass providing your cats are working effiently, just make sure they are nice and hot, like if you are on the waiting line bring your RPMs up to like 1500 for a while, the hotter the cat is the better it will work....its what i did with 91 after i did the plugs/wires/cap and rotor and my car sat for about 8 years
