2nd birthday bling

My monnie is coming up to her second birthday and I’m looking to get her a few sparkly bits. The belly pan is on order as are a few trinkets from Rizoma. I've been struggling with the price of the aftermarket cans and eventually I've come down to what seems to be a cheap but quality item. Arrow make aluminium can called ‘Dark Line’. They are advertised on the B and C Express website for just under £480 inc tax but without Cat. That’s half the price of an equivalent Zard, Mivv or Akrapovic system and probably a third of the Termi system. Anybody tell me if they have any experience of these. Should I avoid aluminium and what’s the story with the lack of Cat, is this going to be an MOT problem?

The 696 doesn’t appear on the Arrows website anymore, have they decided not to build for some Ducatis now...shame

Come on, you know you have an opinion
