US 8,985,260 B2 · Vehicle including exhaust system attached to sub-frame

Abstract

A vehicle includes a frame, an engine, and an exhaust system. The frame includes a main frame and a sub-frame movably attached to the main frame. The sub-frame includes an exhaust bracket that includes a hollow collar. The engine includes an engine casing and an exhaust port. The engine is releasably attached to the sub-frame. The exhaust system includes a conduit, a conduit bracket, and a muffler. The conduit includes an upstream end and a downstream end. The upstream end is connected to the exhaust port. The conduit bracket includes a first end and a second end. The first end is attached to the conduit at a location intermediate the upstream end of the conduit and the downstream end of the conduit. The second end of the conduit bracket is movably attached to the hollow collar. The muffler is attached to the downstream end of the conduit.
