Default Restrictions from mufflers

Does anyone have any real world data backing up what they gained/lost by adding or removing a muffler to one of these pickups. I'm just wondering if I am living in fairy tale land thinking I should have a muffler on mine.

It's a 2014, 363sxe, dual fuelers, MPD piping kit, etc.

It has 5in exhaust and the drone when towing after the sxe swap was unbelievably unbearable. So I threw on a 48in donaldson muffler, it's a big pig.

My mileage has always been ****, and EGTs seem higher than others with my comparable setup, and just overall just seems to run hotter than it should.

Doesn't feel like a loss of power, it's an absolute animal and is a blast to drive, just wondering if I'm leaving a ton of mileage and heat loss on the table by running this muffler?

Thanks in advance.
