We report improvements to our atom-interferometer based Sagnac gyroscope which uses stimulated Raman transitions to manipulate atomic wavepackets of cesium atoms. Using counter-propagating high-flux atomic beams, we form two interferometers with opposite Sagnac phase shifts that share key components such as Raman atomic state manipulation beams. Subtracting the two interferometer signals allows the common-mode rejection of spurious noise sources and various systematic effects. Preliminary results indicate a short term sensitivity of 3 $MUL 10$+$MIN@9$/ (rad/s) $ROOT Hz.
