Recently I have been noticing some new sounds on my Si. Between 3.5k and 4k rpm when letting of throttle quickly there is a swell in engine volume and sort of a raspy rattle drone type sound as the revs fall between those rpms. I only am noticing it the past couple thousand miles. There are 31,xxx miles on the car. Completely stock. I changed the air filter to an AEM drop in about 5,000 miles ago-could a drop in filter really change sound to that degree?
Also I am noticing a whining noise in higher gears, usually 4th and 5th. Gets louder when I add a little gas but I can still hear it off throttle. Is this gear whine? Planning on changing MTF soon. Any ideas? Thanks!
