1971 Dodge Dart PARTS AND ADVICE NEEDED

So im currently restoring a 1971 Dodge Dart with my Dad and we are gonna be swapping out the motor from a slant six to a 318. We have the exhaust manifolds but I need the exhaust, does any one happen to have good exhausts for sale? I'm also looking to change to electric ignition instead of points. Does anyone have Electronic ignition distributor and wires?
