My Mercedes Benz E500 with exhaust muffler removed, and replaced with 2.5" ceramic coated aluminized steel piping. Tips are AMGstyle quad ovals.
Stock cats, and resonator.
Good V8 growl at partial or WOT, but unbearable drone under load around 13001800 RPM.
Props to my brother who's filming despite being dispersed with exhaust fumes and the concentrated noise of an enclosed garage.
