I have an 87 4.2/5sp. PO had removed catalytic converter and exhaust and installed a glass pack. PO also pulled all of the pulse-air system. I did the Nutter bypass and installed a Weber carb.
The glass pack is extremely loud, too loud when driving topless. In addition, the pipe ends right in front of the rear axle, pointing down so I worry about CO gasses. I want to install a normal muffler with an exhaust pipe that comes out the back like it should, and a catalytic converter to be legal.
Question is, would a catalytic converter still work with all of the pulse-air and other stuff disconnected?
