The pipe on the kawasaki is not a Torque Engineering pipe. No '76 is just a general thing but based on what i have seen with pipes on ebay etc, it seems that the factory only started putting the part numbers on them when they were building pipes in the late 70's and for bikes that were current then. Aslo the heat sheild attachment method seems to change in later years. Early made ones had welded on nuts and used screws, later ones have welded on studs and use lock nuts. This is how my pipe is done. Its simple, if it has part number, then i can look it up in the Torque Eng. books and ID it. No part number then your stuck wit ID'ing it purely by sight and test fitting.
