Pics of my new S5 + exhaust question

[Crispystork]

hey guys couldn't figure out how to post pics so the link is below:

I'm thinking of getting a Miltek Non Resonated Cat back. Couple of questions:

Does it make your insurance ridiculously expensive?
How much would it roughly cost in the UK inc. labour?
Would there be a large amount of drone with non-res? If so is Resonated better?

cheers
