Nope, it's gone with that setup. Some 4-into-1 systems do better at keep the low end, than others, but the 4-2-1 you have no chance.

Regardless of the system or the configuration, the fact that the EXUP is gone, is probably the reason, more than anything else.

For a full system, Akra would not be the answer to your specific needs either. If I recall the name correctly, there were systems such as Muzzy that produce better low & midrange (but less topend) power.

Even FI bikes get affected if the EXUP is removed. It is easier though to adjust and to lessen the impact than on a carbed bike.
