the reason i posted this is that i could not find where the noise is from and would like some guesses from other car owners or if someone whos had the same problem before could help me out. ive been to a couple of mechanics and they didnt find where the noise ifs coming from and thought it sounds NORMAL.. it is not obvious if you rev and listen near the engine bay, but when your sitting in the car with windows shut you can hear it like whats in my video. The car has an aftermarket exhaust which i do not know what brand it is, could it be the exhaust? i doubt it though.
