Just spoke to these guys consists of, remove the DPF, take out the internal filters, refit, remove DPF regeneration from ECU, remap to suit £450 all in.
I've seen 1 review so far from a chap over on bmwland forum, 14 months passed and no issues. Lots of happy comments from users via there facebook page.
I was holding out for Evolve but there not having much luck with getting the new DPF pipe replacement from Supersprint. To be fair I don't care much for a shinny stainless pipe it will only draw more attention to itself by a nosey MOT guy...
Anyone else to consider?
