OK I have read through a few threads but have not gotten a complete answer. Ok there is this thing ( i think it was called a silencer in another thread) that conects to the stock filter box. I have taken it off and I can hear a slightly better tone from the engine. What i want to know is that does the car work better with the thing on or off??? I mean does it suck HOT air in withot it or should it be fine without the thing.....and should there be ANY noticable power gains?
