install exhaust before break-in is done?

i picked up a graves slip-on, is it okay to put this on midway through break-in or should i wait until break-in is done

THe only problem with this is YOUR GOING TO REV IT MORE!!!!! If you can control your twist of the wrist urges there is no issue. Engine will breath a little better.

No problem, my brand new bike came with a slip-on........might want to get a filter and PCIII though......
