My car passed with an altered suspension, no cat, and no reverse lights........having connections is a beautiful thing

yes, your car will pass with no front tag and should pass even if the rear wiper does not work and no, your car will not pass if there are any brake warning lights lit up

lowered suspension: you should not have any problems provided there is no part of the car dragging on the ground.

aftermarket cats: shouldn't have any problems there either, although that depends on how anal or knowlegeble the inspector is. Technically, they can fail you for aftermarket cats. But basically, if it looks stock and is in the stock location you should be ok.
