ABSTRACT:
An exhaust hose for an internal combustion engine is encase in a screen sleeve. The hose has a metal tube on the inside which can withstand the temperatures of the internal combustion exhaust fumes. The metal tube has ribs which enable it to be bent without kinking, but also provides significant strength to the hose. A thermal insulation layer is placed around the metal tube. The thermal insulation layer may include a gauze wrapping, allowing the inner portion of the thermal insulation layer to breath. The screen sleeve provides an outer layer for the exhaust hose. Preferably the screen sleeve is slightly larger in diameter than the thermally insulated metal tube, such that the screen sleeve fits loosely.
