Suppose $F: \mathbb{R}^{N} \rightarrow [0, +\infty)$ be a convex function ofclass $C^{2}(\mathbb{R}^{N} \backslash \{0\})$ which is even and positivelyhomogeneous of degree 1. We denote $\gamma_1=\inf\limits_{u\in W^{1,N}_{0}(\Omega)\backslash \{0\}}\frac{\int_{\Omega}F^{N}(\nabla u)dx}{\|u\|_p^N},$ and define the norm $\|u\|_{N,F,\gamma,p}=\bigg(\int_{\Omega}F^{N}(\nabla u)dx-\gamma\| u\|_p^N\bigg)^{\frac{1}{N}}.$Let $\Omega\subset \mathbb{R}^{N}(N\geq 2)$ be a smooth bounded domain. Thenfor $p> 1$ and $0\leq \gamma <\gamma_1$, we have $$ \sup_{u\in W^{1,N}_{0}(\Omega), \|u\|_{N,F,\gamma, p}\leq 1}\int_{\Omega}e^{\lambda|u|^{\frac{N}{N-1}}}dx<+\infty, $$ where $0<\lambda \leq\lambda_{N}=N^{\frac{N}{N-1}} \kappa_{N}^{\frac{1}{N-1}}$ and $\kappa_{N}$ isthe volume of a unit Wulff ball. Moreover, by using blow-up analysis andcapacity technique, we prove that the supremum can be attained for any $0\leq\gamma <\gamma_1$.
