An exhaust may help if you replace the ENTIRE exhaust, including high flow cats. If you are thinking about just a cat back system, that buys you nothing.

You could certainly add a tune but not sure you would get the desired results.

Your best bang for the buck would be to send the '15 up the road and get a '19.

But, the 2019 being a smaller vehicle, does it still have the same towing rating?

No, it is a bit less. With the 3.6 and the towing package the trailer limit is 4000 pounds. If I recall correctly the older Acadia was 5000 pounds.

Personally, if I am towing something that heavy I would have diesel powered Silverado.

I used to tow a 6,500 pound boat with a GMC Suburban. (back in those days they called them Suburbans) Had no problems. It was an easy two. Well, there was one problem. The 11mpg fuel economy. Good thing I had a 40 gallon tank.

I towed a lot with my 2010 and 2012 Acadia, bottom line... fuel consumption is absolutely terrible when towing.

The best way to reduce fuel consumption, lower engine coolant temperature, and to be happy with the power is to simply use gear setting L.

Around town use L3 (uses only 1st thru 3rd gears)
More country roads use L4
Flat freeway driving, use L5 and keep it at 60 mph or under

Feels like you are using more fuel because your RPM is higher, but it actually is using less because you are not under as much load with the engine running closer to peak HP range.

I towed a 6000 lb travel trailer with both my Sierra 1500 (very similar to the suburban) and with the Acadia. The truck was way better on fuel then the SUV was.

Back when I have the GMC Suburban the term SUV had not even been coined.
