In our contribution we study stochastic models in one space dimension withtwo conservation laws. One model is the coupled continuum stochastic Burgersequation, for which each current is a sum of quadratic non-linearities, lineardiffusion, and spacetime white noise. The second model is a two-lane stochasticlattice gas. As distinct from previous studies, the two conserved densities aretuned such that the flux Jacobian, a $2 \times 2$ matrix, has coincidingeigenvalues. In the steady state, investigated are spacetime correlations ofthe conserved fields and the time-integrated currents at the origin. For aparticular choice of couplings the dynamical exponent 3/2 is confirmed.Furthermore, at these couplings, continuum stochastic Burgers equation andlattice gas are demonstrated to be in the same universality class.
