Hello, dear motor-talkers! I think I found my own personal junk of the month, an “out-of-puff whistle”, which is supposed to imitate a turbo sound. 1. Does that work? And how “real” does that sound? 2. Can’t one do an extreme damage with such an exhaust system, because the exhaust emissions are hindered by such a splash in the tailpipe? 3. How can one!?
