RE: exhaust baffle
First off, Congratulations on the bike.
As to the legality of pulling the baffles---Slim to none, and slim just left the building. I've pulled the baffles out of mine and know a lot of people that have done the same. No one I know around herehas been pulled over for loud exhaust. After they've been pulled over is a different story.Some states are more controlling than others though.
You'll just need to remember the exhaust and not go by a cop at 8500 R.P.M.

RE: exhaust baffle
California statutes list two things that can be summarized here:
Muffler required. No muffler or exhaust system shall be equipped with a cutout, bypass or similar device.
Maximum Sound Level. Maximum allowable A-weighted sound levels based on measurements taken at a distance of 50 ft from center lane of travel:1)Pre-1970..92dba; 2) After 1969, and before 1973...88dba; 3) After 1972, and before 1975...86dba; 4) After 1974, and before 1986...83dba; 5) After 1985...80dba
That means that legally any V-Rod would have to be very quiet. Legally you would not be able to pull the baffle(s) out of any bike, as I exceed 92 dba close to idle. (the pre-1970 statute)
That being said, every state has some sort of language restricting exhaust volume but in some states it is rarely followed....and even more rarely enforced. I don't live in California, you'd have to make that decision.

RE: exhaust baffle
You've done about as much as you canSKJOLD, I have the S.E.16 gauge pipes that have a 6mm screw that holds the baffles in. Once removed the baffles can be slid out entirely.
I have heard of larger/more holes but it's kind of a crap-shoot on where to go and where to stop when drilling. The other advantage with the 16s is thatone can put the baffles back in if need be, an option that you do not have when drilling out the stock baffles.

RE: exhaust baffle
It does sound a lot better then stock with the 1/2 holes, alittle tinny but still much better.

RE: exhaust baffle
Move to Missouri....no exhaust restrictions.
Seriously, I would drill 8 holes, 3/8 to 1/2" around the exhaust outlet. Sound improvement is significant, and yet it will not attract attention. You can email me for the instructions or go to 1130.com and search "Exhaust" and find dozens of articles on the topic.
Good luck with your new bike!
