Howdy. There are too many threads that have "key" in them so it's hard for me to tell what's what. My question regards picking up a new or used exhaust system that doesn't have a key. I recently installed the Tuneboy tune & cruise in the bike. With the tune side of it I shouldn't have to worry about whether or not a system I buy comes with a key, right? Because I can use the tuning files Tuneboy provides. Just checking. Thanks.
