good work going on there. Which discs are those, any good ?

MTEC discs and mintex pads

Nice one mate, pics are showing lovely jubbly

fresh discs look great

real noob question but whats the difference in the pre and post mountune exhausts?

I think one was made by a company called BMA or BMC or something, they went belly up so they got Milltek to make them. So its a Mountune specific exhaust and NOT a Milltek, just made by Milltek.

Oh ok, so there's no difference in the tips, note or anything?

Noise is a little different i think, not too much difference. Dan_The_Man should know more
