I designed a new, compact muffler and am in process of making a pair of prototypes
to fly and test.
Wont be available for a couple of months. Units are all 304 SS, TIG welded and
cylindrical for minimum cowl space and
attachment to engine. As I get closer to testing, will inform Pulsar group of results
and possible sales.
