    New Old Stock - Genuine Ford - Dual Exhaust "Trumpets" for the 1965-1966 Mustang GT. There is one left & one right.

    These original Ford exhaust tips are in good - NOS - condition - but showing some surface rusting on the steel pipes. One has scratches & dings that encircle the stainless trumpet end (photos #4 thru 9). That same pipe also has scratches on the black louver (photos #11, 12, 13). Each pipe is stamped with a Ford engineering #. They have never been installed on a vehicle. Both original boxes are in very rough condition.
