I'm helping out a builder working on a government sponsored project that is p=
owered by a Mazda Renesis.   I thought the muffler was a total joke when I s=
aw that it had an unobstructed path right through it.  There is no glass or o=
ther fiber packing in it.   It's 6" in diameter and about 20" long.   There a=
re two of these in series on this installation but I still didn't think it w=
ould be effective.   =20

When I got the engine running I was astounded at how good it sounded.   The o=
nly thing that sounded half as good was Dennis H's  setup (which sounds grea=
t).   I only had it up to 3000 rpm so far but I'm encouraged enough to try o=
ne myself.  I'll get this thing tied down and do a full power runup before o=
rdering though.

Muffler says "Aero Turbine"  on it and is made of 304 stainless.  Google it t=
o see internal construction.  It is quite novel.
