The only problem Bobby is in the flying tests those RV-8s did at
Vans they complained the exhaust was very loud. To the point of objectional.
Make sure you hear one Before paying. I think 87 would be great but a quiet
car is around 87db (at 50 ft) so be sure they tell you where they got that
number. (hopefully not a 10K ft flyover!)

Subject: [FlyRotary] Powersport Exhaust Kit
I posted this to the ACRE group as well so you may
see it twice.
In a couple of
weeks Powersport plans to offer their exhaust as a kit. This is the system
that is running on the two RV8's. Ray indicated they are measuring 81db and
has a sound like a quiet turbine. They have over 80 hours on each aircraft
with no sign destruction. The system uses machined flanges (no welds) and some
inconel parts. The muffler is located in the cowl and is heat shielded with
stainless. I have spoken with them a couple of times this week about the kit
and a set of flanges to support the Renesis. I have offered to send them
an exhaust gasket to use as a template to develop a Renesis flange set. I also
ask them to determine what the minimum first production run would be and what
they would cost. Ray said to expect the kit information to be on their web
site in a couple of weeks.
