can anyone tell me is there much difference between a car mapped with the standard downpipe, cat delete pipe, striaght centre section and drager style back box compared to a car mapped with sportcat downpipe and the other bits i have mentioned? Just looking at my options. Do i really need a sportcat or does the standard downpipe give similar figures. is use my car everyday for work etc and do about 16000 miles a year. The sportcat is a lot of money and am just trying to decide if it is worth getting.
cheers
