Project O2 Dump

The largest dp flange that will bolt up is 2.5" so that would be the optimal size. You could try and go larger but I am not sure you can. Are you cutting the flanges off and welding on new pipe? If so, this may not work depending on the metals you use. The stocker is cast. You can buy flanges seperatly or make your own. I wouldn't cut the old one.
