Sports cat recommendation for bwa with k03

[chrimbo]

Appreciate a recommendation for sports cat for my mk5 with bwa and k03.

Searched everywhere for a type approved one but can't find one. Does anyone know whether it's possible to get a sports cat for a mk5 that's type approved? 

Should I even worry about whether it's type approved provided it passes an emissions test? Good to get your thoughts.
Cheers.
