I have a GHL header and the droning experience. And that happens with both my homemade straight shot muffler/cat, and the GHL dual outlet muffler (no cat). It's quite irritating but the drone disappears above 3k.

Trouble is, 3k in 5th gear is a bit faster than the local constabulary have a tolerance for.
