just fitted the 57i K&N induction kit to my cupra R, I'm amazed as to how loud it is, i had a K&N on my 350z and i swear it wasnt this loud?? sounds so much like a dump valve aswell, im kinda worried something isnt right 
anyone else fitted one and thought the same? or am i just use to a quiet 350?
