Just fitted a Pipercross induction kit to my 2000 wrx uk wagon. Sounds very loud, like a loud whistling when accelarating and a huge dump when easing off power. Should the dump be this loud even without a dv?
yep, its normal m8, mine was exacltly the same. Its just the turbo induction & recirc air blowing back into the inlet and you got no air box to supress the sound.
