Good question. These are 3.5" (~90mm) outer diameter. Stock tips are 3.125" OD (~80mm). The pipe side of the tip is 2.5"OD. I measured the OEM pipe to be 2.35"OD, so (depending on stock pipe wall thickness) the installer will need to flare/swedge the OEM side just a tad to slip these in and weld (common practice).
