Gases are coming out of both sides but the burble and grunt is coming out of the left side only. That tells me there is not enough pressure on the right side.
Just did a cold start, again steam was coming out of both sides but only the left side was giving the sport note.

If the exhaust gases are coming out, then it is open to that side. Do you think it's just the valve not opening and maybe a problem with that vacuum line feeding the actuator arm or something? Or a stuck arm? Have you tried opening the valve manually with the car off?
