The X12 buses do 71 only because the X12 is a smaller and lighter engine then then ISX12. No Jake Brake, they have the Cummins E Brake, which is an exhaust brake. The ISX12 has the C Brake which compresses the sound of the engine brake so you can’t hear it outside, and inside of the bus you really only hear the transmission downshifting.
