Yup. When my exhaust fell off, I replaced it with straight pipe because it was the cheapest option. I also don’t rev my engine through neighborhoods, so no body cares. I can’t tell much of a noise difference in or out. I think the turbocharger did most of the damping.
For a short time I worked in a factory that made school busses. They used big diesel engines and not a single one of them had a muffler. The SCR and the turbo made them plenty quiet.

In a lot of places a turbo is considered a muffler or sound damping device which allows for exhausts to be straight piped after the turbo legally.
Did this with my WRX. Kept the cats but everything behind them was pretty much just a tube with nice looking tips at the end

All my cars are straight-piped. They still aren’t that particularly loud.
