If you are talking about the belt driven air pump mounted above the Power Steering, then yes. My 86 D150 had this pump on its slant six too, and it was not connect to the exhaust. So in the junk heap it went. It is called the A.I.R. pump if I remember, and was supposed to act like an EGR or inject air into the tailpipe to clean up emissions. There is a vacuum line running to it, I did not care since half the emissions systems were disconected on my truck. Look at a diagram though it may mess with something else, or screw up you emissions test depending on your state. Michigan does not test any of that.
The smog pump is designed to help clean the air the exits the exhaust. It might actually be detrimental to remove it if you have to pass emissions testing.
The easiest method is to remove it, and plug the ports on exhaust manifolds and catalytic converter.

To remove the smog pump pulley on a 1992 Ford Thunderbird 5.0, first, relieve the tension on the serpentine belt by using a wrench to turn the tensioner pulley. Next, use a socket and ratchet to remove the bolts securing the smog pump pulley to the pump. Once the bolts are removed, carefully pull the pulley off the smog pump shaft. Make sure to inspect the pulley and shaft for wear or damage before reassembly.
Your best bet is to keep the smog pump in the truck. Just take the guts out of it, this will allow the pully to spin freely. Most states require the smog pump for inspection. Thank god it's only a visual.
