All you have to do is create a bottom 'surface' over the angled void. Easy!

That’s pretty much what I did with the cardboard. It was just taped on and flush with the existing angle. It was mostly flat but slightly sloped up. Could barely notice. Only weird thing is this gap that’s lifted. I wonder why Hyundai did this? Styling? Easier for air passing over the muffler to escape and not get trapped?
With the cardboard diffuser attached to the lower sides, it lift about an inch air gap where that horizontal slit is. I figured in my final design I’ll leave that small slit there to allow any possible trapped air underneath to escape and maybe it’ll act as a light vent for hot trapped air around the muffler to leave. Don’t want really hot air pressure building up back there
