Technician A is correct because exhaust leaks can cause the engine to take in more air than it should, leading to a lean air-fuel mixture that can cause poor performance, misfires, and even engine damage. 
Technician B is also correct because exhaust leaks can allow harmful gases such as carbon monoxide to enter the cabin of the vehicle, which can be highly dangerous to customers driving their car.
