You can cut the pipes open or try to break the baffles loose in the stock mufflers (some guys have done it with a broomstick) and basically "gut them." You might have a hard time finding baffles that will just bolt in, since they are a large diameter can but there's probably something out there.
One thing you can try, if you want to keep the stock look on the pipes and open them up for better sound, is to consider the Sturgis Thunder Pipe Works modification. It's somewhat pricey (almost as much as some of the cheaper full aftermarket exhaust), but they do sound great. But, I'd warn you to consider whether or not you will upgrade the airbox to an aftermarket one before you would get this modification done. I had a time trying to get mine tuned and ended up selling my STPW modded pipes when I changed out to an aftermarket airbox/kit. If you want to leave the stock airbox on it and go no farther than probably just adding a K&N filter to it and shimming the needle a little (like one or two shims), then STPW pipes would be a very good option for you.
Otherwise, you'll probably just want to go with a full aftermarket exhaust. BTW, if you take the stock tips off you might have a gap in your chrome with one of the tips you're talking about in the picture (most likely). I'd measure carefully before spending the money on doing that.
