- the second exhaust avoids a stall, and does not block the system.
- the "main” magnetic exhaust for example, has a better performance because it operates without friction and is, for example, "constant force". it is still silent and has good chronometric properties. It may however present a safety problem, and stall in case of shock or over-torque at the mobile exhaust.
- the second additional exhaust mechanical type, robust but lower efficiency and hardly constant force, just takes over when the torque is extreme for the first exhaust. Both Combined exhausts are therefore complementary and generally have better properties.
