Hi all i have just bought an audi s1 on a 15 plate low mileage car and i can now see what all the fuss is about these are something special! looking at the car it seens to have a straight pipe thru the middle of the car with standard back box and tail pipes , flew thru mot so must have been done correctly, do you think it will have had a remap ? Im in Co Durham any one know where i could get this checked out
