The first thing you can do is find out what the carb was rebuilt with. If an aftermarket carb kit was used, that could be it. They pretty much suck.
For the exhaust, the stock muffler should work ok. Expansion chambers for more power was available back in the day. Both for low end torque and for top end power. They sometimes appear on ebay. Today you'll have to make your own chamber.

Whisperin' Smith Torque Chamber

Bill Wirges Chamber (Aaron bought this)
