On my wife's sporty, she has just broken it in and now she wants a little rumble. However, she's not concerned with squeezing every last ounce of power out of the bike. So, my question is this: Is it safe to just change out the exhaust without doing the air filter change + jet kit install? I'll probably do all of these changes to her bike eventually, but the only thing I'd like to do right now is change out the slip-ons.
Thanks!
Thanks!
