If you remove the baffles, or otherwise modify the exhaust, be careful to check the plugs often for a while. You will probably find that the bike will need to have the carbs rejetted a bit richer. Running too lean will overheat the engine, which is NOT good. Also, if you do this, you will probably have a drop in gas milage. With the cost of gas going up as fast as it is, that also is a consideration.
