Do the mufflers have any baffles or packing or anything inside?

I'd be willing to be you could get away with not jetting. You can put a 4-1 pipe with a baffled exhaust on a lot of bikes and no jetting is required so with you just replacing muffler I'd say your safe. Cheers.

I agree, with such a simple change I doubt you would need to rejet. Be sure and read your plugs after riding it a bit with the new pipes.
