Deuce engine vibration

Well I hope to contribute back some when I do this electric power steering mod. Not sure how it will work, It looks as if I will be a guinea pig test for this. I haven't seen it on the forum yet... maybe I just overlooked it. Won't get into the details yet... don't want to jinx it! Haha. I was looking at possible stack routing options for moving stack of fender to the back of cab. I think it is cool on the fender but it is insanely loud. Read that moving it will quiet it a bit. Torn because I like the fender stack and sound but something needs to be done! Haha. Looked into spray on bedliner for inside the cab also. I did spray the underside of the removable drive train access panels.... I don't think that made any real noticeable difference, but it's only like 10% of where all that sound can come from.

Update. There has been a "wobble" develop at low rpms. I don't hear anything change with engine operatin sound. I am researching harmonic balance and am thinking maybe that is the issue. Wonder if that is ca using the high rpm vibration issue/sound as well. I will be reading more on harming balancer information. Any thoughts on best way to test this? Thanks.

go drive around, run engine a while, shut down and take heat gun to harmonic balancer.
How hot is it?
