Carven Progressive Highway Drone - J-Pipe Question

I used to have a 2016 Ram 1500 Sport with Carven Progressive exhaust + 5” black tips. I loved it. Never had any issues. Now I have a 2017 Ram 1500 Rebel. I just put the exact same exhaust on it and…around the city I love it. On the highway I can’t stand it. SO much drone. I don’t know if I’m just finding out I got old or what but little surprised.

Google pointed me to Helmholtz Resonator, otherwise known as a J-Pipe as a solution. Any recommendations? I spend most of my time on the highway. I need to fix this.
