Well, tested the new exhaust --- calling it version 3.3. Redneck engineering at it's not so finest! Used the cut off manifold flange from an old muffler, added a conduit connector, threaded on a used water heater copper flex line, and re-used the riding mower muffler with the stainless steel scrubby stuffed in it. So far it works just dandy. Maybe I'll try an extended ride this weekend to see if it's really OK......LOL!
