hello a couple ways to do it
#1 any good muffler place can do a custom dual for your car
#2 depending on your model im sure you could buy the stock dual system
#3 if you just want the dual look (2 tail pipes)you can go that way
BTW im not sure what your final out come is so more info may be helpful
including the model of the classic GOOD LUCK hope this helps

This engine does not respond to modifications, the heads have extremely small ports and a cam change is useless, find a decent set of heads, then maybe.
