Bought New Old Stock Exhaust

Hi All
I got my hands on this "highway hawk fatpipes" exhaust.
The retailer had it tucked away since 2011, still new in the box.

Its meant for the 125cc version.
But after reading stories on this forum, they sometimes just need a little bend, to clear the lower frame. Other than that, they should fit.

I havent really dealt with, the exhaust part yet on this bike.

Can anyone tell me what I need?
Like exhaust collars


and stuff.
Its 35mm in the picture.
