Engine, transmission issue? Does not have much power and sounds loud. on 2007 Jeep Commander

When I step on the gas it makes a loud humming sound and when I take my foot of the gas it makes no sound at all. It seems to struggle at higher speeds? Any suggestions.

Sounds like an exhaust flow issue. Check the flexpipe for leaks (between engine and catalytic converter) Possible that the cat. is failing and plugging causing backpressure to choke the engine under a load and may have ruptured the flexpipe (the weakest exhaust link).
