    Default 09 sporty exhaust options

    the old lady wants me to change the exhaust on her 2009 sporty. it currently has the stock mufflers on it. my question is, will i be doing any damage if i chop the mufflers off? and would it be a wise idea to drill through the exhaust and attach eye bots (as i've read on a few forums) once the cut is made? it's an efi so i'm trying to cover my bases before i make a rash decision. thanks in advance.

    Not sure what you mean by eye bots, but taking the mufflers off won't do much harm. If you change the exhaust AND the intake, you'll need to mess with the tuning. On the EFI bikes you'll need to run something like the power commander, to tune it correctly for your setup.

    You probably won't notice much if you just remove the mufflers, other than it'll sound a lot better.
