Legal Eagle Flying Adventures

Over the years I have tried several options, First one was the exhaust tips used on a VW engine exhaust on each end of my 1/2Vw engine. Worked great except they clog up and HP goes to slightly north of zero. This test shows using two can mufflers, from Tractor and aircraft supply, reduces sound by about 6 dBa which is about 50% reduction, with a total weight add of approximately 3 pounds, by the time exhaust pipe stabilizers are added.
