Car: 95 Accord

A friends of mines car recently started sounding like an airplane. No joke lol. I thought at first maybe it was an exhaust leak. After jacking the car up and inspecting down below everything seemed up to par. Also i reved it while it was on jack stands and the noise doesnt exist.

Sound only comes underload. I got a sound clip of it and its around 14 sec mark. I dont know to much about the accords so hoping to find some help from you guys.

I also thought maybe it was perhaps the tires but she claims it just begun about a month ago.

Anyhow heres the clip!



Thanks in advanced guys,

Mondo
