However got massive drone now with top closed. Thankfully it's almost always down. Top down is awesome and no problems. Kinda wanna go louder but can't tolerate any more drone with top closed lol

Other than headers, is the rest of your exhaust stock? |
Just stromung mufflers |
That explains it, changing section 3 (mufflers) will cause the most drastic changes in tone and induce drone from my experience. Just headers alone shouldn't have any drone.
