Bootleveg, I would guess in most areas that was not in major cities like LA or NY the sewer lines are small. In our area the only way they have of checking them is a very big truck that caries a very long camera. It just unwinds and takes pictures of the sewer. That is why I said if you saw someone around you might want to shut her down until there gone. The chance of any exhaust from you engine causing an explosion would be minimal campared to sewer gas, as long as it was cool or even cold when it hit the pipe you should be OK. I suppose some politic an at the city might think different. I plan my exhaust to run 20 or 30 feet under ground and the slope of our ground I will build a little place for it to exit like you would a water drain. The pipe in some places will be about 30 inches under ground. That should absorb most of the noise and with the pipe sloping down any build up should flow out of the pipe. I plan for my pipe to run under my green house to claim a little heat from the exhaust. I also plan to build a heat exchanger but that will not be until next year. I still haven't decided how I would like to make it. Mike
