Bad idea sur la nouvelle gen, en gros:
A twin scroll turbo relies on an equal length header to function properly. Actually one of the largest limiting factors in a single scroll turbo setup is the unequal length header.
There is no way to have the distinct rumble you are looking for on the new WRXs. The twin scroll turbo was designed to take advantage of how the air is delivered to it, and the equal length header is the best way to do that. Basically because of the equal length header, more air can exit the combustion chamber, and the turbo can push more air into the combustion chamber resulting in a denser charge, a bigger bang, and as a result, more power.
