yesterday i got 40miles to £10 and usually i get about 65 to £10 :wacko:

more than likely because you were driving it a bit harder because it sounds so much nicer with it on mate

Did you go for a drive to test if it was faster? If so u where probably driving harder/faster.

Made mine better on petrol if anything. Can easily get over 100 miles to a tenner if I take it easy.
