EGR won't affect your power unless it's stuck open, if it was me i'd bin it anyway though.
Imho after-market panel filters are a waste of money, but everyone has their own views on that.
Mpg - if you drive it hard it'll use a lot of fuel, if you drive it nicely it won't be any different from before, in fact a lot of people see their every-day mpg go up after a remap.
Exhaust - mid-box is pretty much straight through already, so most people get rid of the back-box and cat and use the mid as their only box. Would advise against spending money on an after-market back-box as they're all designed for petrols so will most likely cost you power.
