That may well work, John. Early on I took some 0.065
SS tubing drilled holes in it and and squished it down to form "fish
tails". They certainly made a difference even though they were only
18" long. One fell off during taxi after doing some repair work at Tracy
Crooks on one visit and Tracy immediately noted the difference in sound.
The only problem was while it reduced the exhaust note from
"ear shattering" to "Damn loud" it was still too loud.
But your idea would be cheaper than the cones - if only I
had a welder and could weld (keep meaning to do something about
that).

Ed; What's your thoughts on cutting the
exhaust pipe off on a long angle, maybe six inches in length, drill holes in a
piece of SS plate,of .060", then weld the pipe back together with the plate in
the pipe. This would give the angle of the funnel with out the $60.00
outlay. Working on exhaust system, which is 2 1/2"s in dia.
