This document is a simple hand-drawn schematic (apparently made in a basic paint program) showing a proposed or existing dual exhaust routing on a vehicle, filed by the uploader under their 1991 Ford Bronco. The drawing is a top-down (underside) view of the vehicle: grey lines represent the frame, black lines represent the body outline (including four wheel/tire rectangles and center shapes representing the engine, transmission, and transfer case area), and red lines represent the exhaust routing. The red exhaust path runs from the engine area, with pipes from both sides of the engine converging near the transmission, then splitting and routing rearward along both sides of the driveline, exiting at both the front-passenger area and rear of the vehicle. The only text in the document is the three-item legend: 'frame grey', 'body black', and 'exhaust'. There are no part numbers, dimensions, pipe diameters, muffler locations labeled, or year/model applicability stated anywhere in the drawing. It is one of a set of related drawings in the same album (dual exhaust variants and a single exhaust version), useful mainly as a conceptual routing sketch for planning a dual exhaust system layout.
