Thats exactly what I did! Dented up the headers and moved the exhaust around slightly to have it as far from the frame as I could. The huge KR I was seeing is gone now. I still get blips of 0.5* KR though on stock timing which at this point I believe is the sensors being sensitive and picking up noise from the headers being so thin compared to the manifolds? I also want to try and shut off burst knock first. Any other recommendations?
