Muffler test
Two flight tests totaling 3.5 hours so far
on the Aero Turbine muffler (XL version with resonator built in) on the 20B
powered RV-8. Best muffler tested so far. Quieter than even
the Spintech which was the previous best. The irritating high
frequencies are virtually eliminated from the exhaust. No noticeable
increase in drag. No increase in power or fuel economy either in spite
of claims printed on the box. The beautiful polished 304 stainless
finish disappears pretty quick with the rotaries hot exhaust. If the
muffling performance holds up I'll be very satisfied. At $79.00 it's a
bargain.
