R56 performance upgrade
 

I was hoping someone can recommend performance upgrades for a standard cooper R56. I want it to perform as a cooper s.

Should I get a performance chip, new performance exhaust or sprint booster?

There is no way to get S type performance from a non S car ...
Unless you turbo it....
Intakes/ exhaust /headers/chips can likely only add 15/20 horse

Thats a huge amount of money for a minimal return
