well since you've been having the C30 and the C38, do they sound the same, or is C38 is obviously louder at idle? how does each system whining sound, does it have the same observation (800-1500rpm loudest?)
if what you are saying it's true, then i guess in time i'll have the dust kit on this air filter and the annoying sound will dissipate on it's own!
FYI, i did try to cover up the air filter partially on my own system, i did not notice any change in sound. For it to really change, i would imagine it had to be pretty clogged and likely danger-ing the system if the sound really dampened that much??
