Hello Dan,
This is summat we can help with..

If your going the full hog with all of the above your looking at around 218-225bhp.
If your having a package deal we can do you the Remap, 007p, and pipercross filter and rolling road power runs for
£230 £250 all inc. (you will also get full diagnostics, visual check up of the car on the ramp)
In regards you can have a Miltek system or a custom sports or de-cat with cat back.
I fingers crossed will know more about exhaust prices tomorrow.
Nick
