First off I'm fully stock, other than some new bullitt rims/tires and a K&N air filter.

Lately I've been noticing some noises, I can't tell where they are coming from but I dont know if they are normal or not... It almost sounds like a jet 10K ft. above you, a sound like that (of course quieter than a jet lol). Do you guys' notice these noises in your cars with no roaring exhausts, or are they fairly silent, other than the sound of the road, when you drive?


I dont think it's something rubbing anywhere (though I could be wrong) simply because I dont really feel anything different, and I haven't observed any drop in gas mileage or any other abnormal things. I did notice that below my right foot when I'm on the highway sometimes for a minute or two on cruise control I feel a vibration.

I am due for an oil change-- could that cause some noises?

 

My bet would be road noise from the new tires.

 

I was thinking that too but it just doesn't sound like it. I think tomorrow I'm going to go to the dealer and test drive the mustang they've got for sale (same as mine) and see if it sounds the same
