HI temp hose for routing vehicle Exhaust outside while running inside. 2 inch and 3.5 inch inside diameters. This cost me about $670. few year's ago. Have seen ligh private use. They are 11 feet long with one end larger so can be joined for longer runs. I'm asking 400 for all or $150 each for 3.5 and $75 for 2 inch. Must go will concider trades for building materials.
