Engine Roar

Lately my 5.4 has started to roar at around 2000rpm. Maybe roar isn't the best description it soulds more like the soud you used to get when you opened up a big 4-bbl carb. It didn't used to do this though. Any ideas?

running a K&N in the intake, it was serviced about 4000 miles ago. Thanks, for asking it might need serviced again, i'll check it.

i wouldnt say that has anything to do with being serviced or not, but maybe your just hearing the intake. i woulndt think only a k&n would bring out this noise that much. does it do it at crusin speeds? or jsut when you punch it?
