Ok I have a PiperCross induction kit fitted to my Digifant. I can't compare it to another induction kit coz I brought the car with it on but it does make a decent noise.......its not a subtle noise but its not an annoying load sound either. Decent tone and roar to it. The induction kit is supposed to give u some xtra bhp(probably)....
