Actually, it's your engine kicking
out of overdrive and
into a direct-drive or lower gear ratio.
Louder, yes. Most likely the viscous clutch on the cooling fan. Check to make sure that it hasn't failed.
The Banks kit gives it a nice, throaty growl across the RPM band. The special intake doesn't whistle like some CAI setups do. The headers and larger exhaust definitely change the exhaust note.
