To those interested in just the sensors:

This pipe was from a D2 and the O2 sensors are a little different than the D1. They both work the same, BUT the D1 sensors and holes are threaded differently than the D2. This means you can sawp out Y-pipes, but you can't put D2 sensors in a D1 Y-pipe and vice versa.

Thanks,
