Hi, So I've been on another Ducati forum but this one seems to be more active I would like to have your opinion about a new full system for my XDiavel S. I've found these zard systems for lower price than retail here: https://euromotards.co.uk/product/Z...rd-Exhaust-Full-System-Kit-Black-Silencer-New https://euromotards.co.uk/product/Z...18-Zard-Exhaust-Full-System-Kit-Inox-Silencer So, black or steel? and why does the black so expensive?? BTW, anyone familiar with Ducabike rearsets? or have another recommendation? Thx!
