anyone had any experience with either blue flame or scorpion systems?thinking about a cat back system and probably going for a milltek but the scorpion and blue flame ones look great too but I'm not sure if they're as good as the milltek.im struggling to find any decent pictures of the scorpion one and the manufacturer hasn't replied to me yet. blue flame sent me some photos and it does look a good system but has anyone got any experience with it?loudness/fitment and finish etc?thanks
