anyone tried any of the others out there, apr, jetex, i noticed the eurojet one was very similar to the blueflame one in design, scorpion is similar too, they have got rid of the rear transverse box for better flow, but at a guess i recon they will be louder. iam still toying with the idea of a blueflame because of price mainly, but if they were all £800 i would go for the milltek res
