That's a C5 Corvette manifold. I wish you would have hit me up before you got that F-Body manifold, I have the ones from my 99' sitting on a piece of wood blocking the dog from getting under the fence lol. Speaking of I need to fill that hole soon lol. As far as the Denali, badges, grille, anything that looks cool and in good shape just let me know what they have lol.
