No, the SRC system for the C3 is specific to the C3 shell.
But the SRC-S system is now available for the S2 helmet, and it's actually an updated version of SRC. Cardo makes both systems, and my understanding is that SRC-S is based on Scala G9 while SRC is based on Scala G4. All of the systems are compatible with each other, however.
