why??
Yeah, mine humms and whistles too. It hums because there is no longer a silencer there, thats the whole purpose of it, and the whistling is suposevly normal, at least thats what Acura told me.
the humming is normal like said because there is no silencer and the whistling isn't really a whistle thow it sounds like it a little all it is is when you tap the gas or step on the gas it is the sound of the filter starting to suck in a large amount of air mine does the same thing
