You didn't specify, make sure the car is hot and running when you're checking for the leak at the engine (because your engine is basically idling and is hot when stopped). You may need to unplug the cooling fan so you can detect any small pulses. You could try an aggressive brake torque (if automatic) and watch for smoke at the engine area, this will put high pressure into the exhaust manifold.
Otherwise, your exhaust system extends all the way to the rear, so you may need to get it in the air, while the engine is running, and check out the whole system. Put your hand around and above all the joints and also your ears work good too.
