Welcome JaKal to the HDTimeline forum and your first post. May I ask how long have you been riding your new machine. Part of the deal here is local and state laws are cracking down on the very subject you are talking about. True, the exhaust system has been modified for both EPA emissions and noise requirements and loses about 7-9 HP due to this. That said, you selected the machine for reasons that probably do not circle around that loss.
If you choose to remove the baffles, the bikes' performance will actually DEGRADE, as the rest of the system fueling, pipe tuning, air intake are all balanced for that degree of back pressure, and the high pitched sounds as well as the low pitched ones we all know and enjoy. I woiuld opt with slip-ons and keep the old mufflers in the event laws change in your area. Trust me, it is coming...California Legislature just passed the law to enforce the noise portion of tampering with the exhaust holding the owner accountable...if the emissions portion passed, we would be in bi-annual inspections...not good.
