Does anyone else have som experience with this exhaust or solutions to fix the resonance?

If not, I wil go back to stock or look for the PSE witch i think wil be a more comfortable balance betwen cruising and good sound over 3000 rpm

I have the same exhaust as you. To get rid of the drone I inserted a single motorcycle baffle in the "s" pipe before the muffler. It will eliminate the drone. If you want even more quieter you can wrap the baffle with fiberglass motorcycle wrap. Motorcycles have this problem all the time with aftermarket exhausts.
