???If I replace the stock mufflers on my 81 Special, what happens to performance as there will not be a crossover pipe?

Well, if you do it right, and use a good system, you will pick up some performance. You will have to re-jet the carbs, and while you are doing it, you might want to go to some K&N air filters for better breathing. The biggest concern is to get it jetted properly and use the correct heat range spark plugs, otherwise it will run like crap and you are in danger of frying a piston if you let it run lean. You can do it, it's not a big task.
