I came up with this, I need a quiet exhaust to drive across my neighbors easement, but I WANT a 5" pipe, so I was thinking of instaling an exhaust valve that runs open unless I need it quiet, when closed it diverts exhaust through a small (2.5"?) pipe with at least 1 baffeled muffler, it would only be good for low speed usage, but it would keep me more polite and on good terms
