just fitted a new induction pipe and filter to my 2000(w)1.8t ,the trouble is there is a breather pipe which comes off the hard pipe and it tells me in the instructions that it needs to connect to an inlet pipe close to the dip stick,there is no pipe there to connect up to,so for the time being i have blanked it off.when driving the car it does not sound very loud and when come off the revs to change gear you can hear a flutter noise like a dv but it has no dv and it idles funny.so what is my problem please help
