This is what I received from Awesome.
"Hi
this is so hot off the press Milltek are working on the prices now , but not been released yet , so you are the first to know so keep it secret
The downpipe is £564.50 retail , our price is £508.05 + VAT
The cat back is retail £384.50 + VAT for the non resonated our price would be £364.05 + VAT
Cat back on the resonated would be retail £450.65 + VAT and our price will be £405.59 + VAT
Fitting we have never done one , but as an estimate approx £148.50 + VAT (3 hours)
Hope that helps?
Sarah"
So, it is £914 +VAT + fitting.
I doubt myself if it takes 3hrs to fit though.
