Loved the one I had. I had a k&n cone filter and a blueflame cat back exhaust on and it sounded awesome. Also had a bluefin remap but not worth the money IMO. Deffo relocate the imrc box. Only thing that would put me off is the cost and effort of replacing the clutch as it will take a hammering on track. Also uprate the brakes before you track it!! The standard ones are the same as the 2.0 and they are deadly they just don't stop the car!! St170 discs and mk3 mondeo callipers and pads are the easy cheap upgrade
