Dart exhaust wanted

I recently picked up my first project, a 1970 318 dart sedan. It currently has no exhaust at all, just the exhaust manifold and that's it. Eventually I will want to do more to the exhaust but for now so I can get it registered and rolling I'm looking for stock exhaust. Either single with y pipe or dual exhaust. Complete or partial system, like if its just the down pipe from the manifold even that would be awesome. Let me know what you got. Trying to keep cost on this low cause its just a temporary fix for now. Thanks
