any recommendations for an exhaust system for an ED classic falcon?

2½" redback system, a decent set of extractors and a high flow cat.

Or if you just want a flat out stock replacement, 2¼ press bent mild steel will do the job just fine.

You need to give some indication as to what you want and how much you intend to spend.

3 words of advice though,

You get what you pay for,
Don't expect it to dramatically enhance the performance level of your car
there are plenty of threads on here already in relation to exhaust systems with a cost indication, i do strongly suggest you make friends with the search function. When it works it is very useful.
