I just spoke w/ Ansa in Atlanta, Georgia and they list a rear muffler for 1985 and later Ur's. Does anyone know if their part number AU7007 will fit my '83 Ur? Any experience w/ this muffler? Stock sound levels would be great, not hoping for a race car sound. TIA, - Doug PS - Does anyone know if this thing comes with chrome tips, or the preferred black ones?
