Cutouts for Strip only, beneficial?

Engine masters did a cutout episode deliberately trying to make the cutouts look good. They failed in my opinion
They used a hugely powerful big inch bbc, that should have had a 3 1/2 or 4 inch system with straight thru mufflers.
Instead they used a 2 1/2 system with turbo mufflers (on an 800 hp engine!?!)
Of course the cutout looked good.
But even EM admitted if the cutouts were installed too far back, the engine sounded like ****.
My personal opinion? MOST street driven cars with mild cams sound like **** uncorked.
