I'll slightly disagree with the other reviewer, this item does make a difference, albeit very slight, not like the equivalent item for the mk2.5
a slightly better noise, but mostly only from 4k upwards, which does seem to mean more fuel is used, as the noise if nice :-)
not noticed any fuel difference with normal driving
not really worth the cost, the difference in performance is nill and the difference in noise is only when you are driving like you stole it.
