Exhaust sound... how to slightly improve?

Just run a top fuel drag sound track on a loop.

Happy to report, the DEI Muffler Wrap at 24" x 40" fit perfectly, 1-1/2 wraps around the Borla Muffler, with the double layer on top. Reduced the interior sound to a very slight, low tone. Barely audible at 75 mph on cruise control when going up an incline, with no radio. Turn on the radio, and you dont hear the Borla. https://www.summitracing.com/parts/DEI-010455
