In case anybody was interested in a cheap or free mod if you have a welder.
I chopped off all the exhaust from the muffler back. Using the stock piping, I welded the stock resonator in place of the muffler and made a side dump in front of the rear wheel.
At the same time, I went from a ko2 to km3 which took me from 84lb to 100lb per wheel, yet, it feels more peppy and it hardly downshifts up big grades in SD. At most it unlocked the torque converter towing my jet ski yesterday.
Overall, no drone, just a clean deep, mean sound when on it and throaty when cruising. I will see what it sounds like once the headers go in and I can get a muffler shop to custom fab me a y pipe(not allowed due to Covid)
Here is a video.
