I was just looking through some threads and I have been noticing the air silencer a lot. Is the air silencer only on stock intake? I have CAI with a K&N filter, does that mean my air silencer is gone? If it is not gone, can someone post a pic so I can get rid of it? All I have to do is go to my passanger fender, remove some bolts and thats it right? From my understanding, it is a waste..is this true?
