I installed this bassani y-pipe on a 1997 F250 HD, 351W. It fit the stock manifolds perfectly and cleared everything it needed to. It has 2 differences from the stock y-pipe. The O2 bung is about 2 feet before the stock location, but still upstream of the catalytic converter. It can be used without modification just by using a universal O2 sensor or adding wire. There is an air tube provision for the smog pump; my model has these tubes in the headers. I welded over this. Fit perfectly.
