I have a 2001 Honda accord 5speed. I recently started hearing what I thought was an exhaust leak but now I'm not sure. When I drive the car and get to 40 mph or greater, there is a throaty loud sound coming from the back of the car, almost like an exhaust leak. It continues even with the car in neutral and just coasting until I slow down to below 40 mph. I thought maybe the resonator or something? The only thing I had done recently was I changed the catalytic converter and the o2 sensor. Other than that, I cannot find an exhaust leak or anything that makes the loud sound with the engine idling with the car coasting.

Any ideas?

Thanks in advance for your help

 

Wheel bearing

 

It doesn't seem to be coming from a wheel. Its' not a grinding noise either. It is difficult to explain but it is an exhaust like sound but does seem to be maintaining the noise with the speed of the car and decreases as it slows. The car has 202K miles and is the original muffler. Could it be the noise coming from the muffler somehow?

Thanks,

Exhaust leak like ticking, loud, or sounds like you are driving on sand?
