Ford Ka - Putting noise - Drivethru

I am getting a putting noise from the rear left side when braking. The car has just passed the mot and nothing was mentioned although I suspect the exhaust is on it's way out. Could the noise be from the exhaust or is it likely to be from the brakes?

Thanks.

Get your brakes checked,

And by that I mean wheels/drums of and inspected.
