Trip to Belgium to get a Carnewal exhaust

[JapanRed]

Ive decided to bite the bullet and am going to drive down to Belgium so that Gert can fit me a Carnewal GT exhaust +/- 200-cell cats, to my 997.1 911.

Anyone else considering this? We could potentially make it a bit of a roadtrip.
I'll be going down before christmas.

Can anyone advise on whether to add 200 cell cats or not?

Thanks
Rob
