am hopefully getting a tax rebate from work on friday......touch wood! and am looking at fianlly getting a dump valve for my petrol cupra, and i am stuck as to which one to get
which one...if any...is better for the car or are they the same?
am not really fussed as to how loud they are, but i would like to be able to hear a whoosh when changing gear
Thanks
