I didn't have an impact wrench where I was working at the time. I did buy a gizmo that fits over the manifold and a stud drops down into the head pipe, which I have yet to install, but I did get a donut gasket in the pipe and two studs tightened, and got it to my house with less noise. The P.O. has sawed the factory muffler off and put in a straight pipe, it's not real noisy it has that huge catalytic cnoverter on it.
