There are still some questions around whether 455 cars were able to be optioned with VOE (Ram Air cars were not) I shudder to think what it would have done if it was a legit VOE 455 car.

W73 did not bypass the mufflers. All it did was to adjust the exhaust flow to use less baffles in the standard mufflers. The reason why it was not available on the Ram Air engines was because they came from the factory with high flow, low restriction mufflers.
