Along with David Higgins is Travis Pastrana's 2014 Subaru Impreza WRX STI Red Bull livery, The livery he used in his return to Rally America in 2014, at the Rally in The 100 Acre Wood.
As always, the livery_41 file goes to:
C: Program Files/Steam/steamapps/common/DiRT Rally/cars/models/sti For those who don't know.
The livery replaces the original white livery on the R4 Subaru, I'm pretty sure another Pastrana livery replaces this, so replace the number at the end of each .pssg and the "livery_41" folder if you prefer to replace another livery.
