Who knows.
I doubt if any comparison studies were ever done, with something like that.
I can tell you this much, though.
The Superstock exhaust system that i have, i was told when i got it, that this system was removed, and Jardine Headers were installed in place of this system.
So back in the day, some 64 Superstocker gave up these parts for aftermarket Jardine Headers.
