The pic doesn't work for me but I assume you mean the rear-most tip which is actually attached to the resonator. Mine did the same thing, the resonator is pretty cheap at Rockauto. It connects to the muffler pipe with a flange right above the rear axle. You can grind off the bolts and attach a new resonator. Issues with no tip may be exhaust seeping into the rear plus heated gasses melting your plastics back there. Is it a big deal? Probably not but I didn't like smelling fumes.
