Pipe Diameter Comparison Sketch - 2 Inch vs 1 Inch Diagram (1991 Ford Probe)

This document is a simple line-drawing sketch (labeled as a blueprint) uploaded to a 1991 Ford Probe gallery under the filename "pipe di.JPG", suggesting it depicts pipe diameter comparisons. The drawing shows two rectangles and two circles: a larger rectangle dimensioned with "2\"" on its left side, and a smaller rectangle nested at its lower right dimensioned with "1\"". A large circle overlaps the right side of the larger rectangle, and a smaller circle sits inside it, roughly corresponding to the two rectangle heights. The only text in the document consists of the two dimension labels, 2 inches and 1 inch. There are no part numbers, fuse ratings, wire colors, torque specs, model years, or other identifying information. A reader can learn only the relative size comparison between a 2-inch and a 1-inch dimension, likely pipe diameters or cross-sections given the filename, but the document itself does not state what the shapes represent, what vehicle it applies to, or any measurement context beyond the two labeled dimensions. It cannot be used to confirm or deny applicability to any specific vehicle.
