Is their suppose to be a o-ring in between the exhaust flange and the pipe? it has a new exhuast gasket (Jug to flange). Its a new to me viper with bender pipes and not much of a seal between the to.
no o-ring just a metal gasket, if its leaking you sometimes need to wipe a good smear of high temp rtv on the flange of the pipe manifold and bolt it up and let it dry overnight before starting it up. The aftermarket manifolds are not always nice and flat.
