Exhaust for a 1973 Duster 340 (Pics Included)

There are a lot of options for exhaust. Some expensive, some not so bad. This depends if you can do it yourself and you have a shop to work out of, and can use something prefabricated that bolts or welds together. If you're like most 26 year old guys with their first muscle car, budget is an issue. Drag it down to the local muffler shop. They should be able to get you fixed up from the manifolds back, affordably.
