A method for operating an engine system is provided. The method includes during a first condition, flowing exhaust gas from a first exhaust gas conduit to a first turbine inlet of a turbine and flowing exhaust gas from a second exhaust gas conduit to a turbine bypass conduit and during a second condition, flowing exhaust gas from the first exhaust gas conduit to the first turbine inlet and exhaust gas from the second exhaust gas conduit to a second turbine inlet.

1. A method for controlling boost operation in an engine system, comprising: during a first condition, flowing exhaust gas from a first exhaust gas conduit to a first turbine inlet of a turbine and flowing exhaust gas from a second exhaust gas conduit to a turbine bypass conduit; andduring a second condition, flowing exhaust gas from the first exhaust gas conduit to the first turbine inlet and exhaust gas from the second exhaust gas conduit to a second turbine inlet, and, during the first condition, flowing exhaust gas to an exhaust gas recirculation (EGR) conduit upstream of the first exhaust gas conduit, the EGR conduit coupled to an intake system. 2. The method of claim 1, further comprising, during the second condition, flowing a portion of the exhaust gas from the second exhaust gas conduit to the turbine bypass conduit. 3. The method of claim 2, further comprising, during the first condition, providing boost to an engine via a compressor coupled to the turbine. 4. The method of claim 1, where the first condition is when a catalyst positioned downstream of the turbine bypass conduit is below a threshold temperature and the second condition is when the catalyst is above the threshold temperature. 5. The method of claim 1, further comprising, during the first condition, decreasing a late phase combustion operation where fuel is injected into an engine cylinder during a second time interval subsequent to a first time interval. 6. The method of claim 1, where the turbine bypass conduit is spaced away from a turbine housing. 7. The method of claim 1, further comprising, during the first condition, flowing exhaust gas from the turbine bypass conduit to an emission control device. 8. The method of claim 1, where the first and the second exhaust gas conduits are spaced away from one another. 9. A method for controlling boost operation in an engine system, comprising: during a first condition, flowing exhaust gas from a first exhaust gas conduit to a first turbine inlet of a turbine and flowing exhaust gas from a second exhaust gas conduit to a turbine bypass conduit; andduring a second condition, flowing exhaust gas from the first exhaust gas conduit to the first turbine inlet and exhaust gas from the second exhaust gas conduit to a second turbine inlet, and, during the first condition, decreasing a late phase combustion operation where fuel is injected into an engine cylinder during a second time interval subsequent to a first time interval. 10. The method of claim 9, further comprising, during the second condition, flowing a portion of the exhaust gas from the second exhaust gas conduit to the turbine bypass conduit. 11. The method of claim 10, further comprising, during the first condition, providing boost to an engine via a compressor coupled to the turbine. 12. The method of claim 9, further comprising, during the first condition, flowing exhaust gas to an exhaust gas recirculation (EGR) conduit upstream of the first exhaust gas conduit, the EGR conduit coupled to an intake system. 13. The method of claim 9, where the first condition is when a catalyst positioned downstream of the turbine bypass conduit is below a threshold temperature and the second condition is when the catalyst is above the threshold temperature. 14. The method of claim 9, where the turbine bypass conduit is spaced away from a turbine housing. 15. The method of claim 9, further comprising, during the first condition, flowing exhaust gas from the turbine bypass conduit to an emission control device. 16. The method of claim 9, where the first and the second exhaust gas conduits are spaced away from one another.
