The D.O.R. systems are designed for the person who wants that custom look of a dual exhaust on a late model vehicle that came with a factory single exhaust. These systems feature mandrel bent 16 gauge aluminized steel tubing, either weld-on or flanged inlet pipe/pipes, specially tuned muffler, clamps, hangers and stainless steel exhaust tips for that aggressive look and sound of a dual exhaust system.
