Converting 318 to Dual Exhaust

Unless you are going resto/correct with it buy a set of Dynomax super turbos and hang them.Run an h-pipe and mandrel bent tubing would be best.On a mild 318 2" pipe would work and 2.25 would sound a little louder.If it drones at your cruising rpm's you can intall resonators in the tailpipes to cure it.
