I would want to express my thoughts:
In my opinion, this object likely produces an impressive and authentic sound when subjected to a WOT pull.
My only grievance with very forceful exhaust systems (those without catalytic converters or with high flow catalytic converters, etc.) in turbocharged vehicles is their noise level at low velocities, such as while driving in residential areas. Their sound evokes the resemblance to that of vehicles, which is unpleasant.
I am aware of this since my 992 Porsche Carrera S has a very forceful exhaust system. I experienced discomfort due to its sound at low velocities, however the sound it produced at wide open throttle (WOT) certainly compensated for it.
