I've currently got a Milltek price list sitting by me and the urge to splurge the £646.48 on a full resonated system (I could save a bit with a non resonated system but I don't want it to be loud) that's a turbo back system with a hi flow TDi cat. I have seen a couple of you have Milltek systems did you get the full system with the cat or just the cat back? Dose the car feel different? Are they loud? I was thinking of starting with one of these and a 160 intake before moving onto a chip and bigger stoppers. (What are the standard FR rotors 280mm,312mm?) Is this the sort of way I should be looking to head or would you recommend starting from a different angle?
