A bit of history
05 standard with unifilters (was told by previous owner that it was tuned to suit filters)
As far as I know that is the only mod that has been done
Exhaust system seems stock visibly Altough I can't be certain if any internals have been removed
I have just looked in TuneEcu for the first time and seen what tune is installed (see photo) the description seems wrong somehow
It lists aftermarket silencer and decat but not Pod filters?
Start your bike up and rev it to 3000rpm---if it sounds like a sewing machine then you have the stock exhaust. Pull a plug or two that will tell you everything.
