Specifically listen to the 1991 turbo accelerate, and at 3:52 mark I can hear some resonance really change the pitch of the exhaust. Is this similar to what you are hearing?
Sounded to me like the wastegate opening.
Mark H. 1987 930, GP White, Wevo shifter, Borla exhaust, stock everything else. The result of a massive Pelicanite good will fire recovery effort. Truely an open book, ready for the slippery slopes to modification.
