M5 Competition with OPFs

Chaps,
Here in the UK, our M5 Competitions come with the dreaded OPF filters, which is utter rubbish, when it comes to swapping the full exhaust system. Im told companies are working on a solution, but i already feel that this will not come to fruition, and this is how it will be for good.
My question to the forum, and distributors is, which rear silencer will work best in this situation of OPfs ?. My main aim is to bring out the bangs and cracks that i know are in there, but are very muted at present. I have a choice of a few in my head which are, Remus, AC Schnitzer, and Eisenman sport, not the race version, because i still want the valves function ?.
I know this is probably an unknown quantity to you guys, with not being in this situation, but any help, opinions are appreciated, thankyou

Just had my Keller upper and lower downpipes delivered and the Akrapovic OPF Evolution system. Am assuming i will get a CEL somewhere along the line, but will end up getting them coded out via a DMS tune...

Will keep you guys updated.

Was chatting to a chap recently with a first edition, who had DMS remap his car, and had a full Akra fitted. He says its astounding in the mid range, and speaks very highly of DMS, and said they would stand by any warranty concerns. Got me thinking, even though i dont really want a remap, pretty tempting if they do indeed stand by their product.

Hi Mate,

Akrapovic stand by their system as well. Having spoken to Peron Automotive, the UK distributor, they are 100% confident, they'd stand by their product.

I had a DMS map back in the day on a 335D. There really top end stuff mate.
