Firstly i have only fitted one to the A3 so far, upon fitment the cars turbo seemed to give more of a whistle under acceleration which is nice and not too loud but just noticeable....also the catch can never seems to have anything in it, yes the car gets used on average once a week which might be a factor.
I am going to be doing the S3 soon, plan is just to delete all the pipework under the mani until this catch can group buy gets underway again - did anyone notice any difference upon doing the S3 fitment? whistle etc?
