my rs turbo used to have an 'old' scorpian system on it which was restrictive due to the sharp 90 degree bend at the back of the system. This snapped at the backbox a few weeks ago so I brought another scorpian. When it turned up I was quite surprised to see that all the welds had gone (I think there is 1 on the entire system) and the 90 degree bend has been better shaped like the mongoose so they are no longer restrictive. Its also 2.5 inch straight through the backbox as well !.........so scorpian arnt as bad as every one says
