DON'T RUN
WITHOUT A MUFFLER. Your ears will thank you for it.
Bill Jepson

I don't know what the RX8 has for a muffler arrangement, but it purrs very
queitly.  I was surprised by how quiet it is.  I don't remember the RX7 (12A
or 13B) being so quiet.  Perhaps that's the difference between a new car and
my memories of the older rotaries.  Is the exhaust system or the mufflers on
the RX8 different than what they were for the RX7?  Or, does the side
exhaust arrangement in the Renesis housing lower the volume?
The biggest question, though is this:  How much power (created by back
pressure) does the muffler and catylic converter eat up on a street legal
car versus a slightly muffled engine in an aircraft?

I think the RX8 engine side exhaust may have something to do with it.
