[Fot] Stove pipe silencer.

[Van Mulders Marcel]

Some years agon I modified my silencer of my racecar to reduce the weight :
I kept only the straight through pipe and welded a very light stove pipe
with 5" diameter around it + shutting plates. Because the car got noisy and
I had some difficulties on the race circuits that have strict noise
policies, I opened the silencer. Almost nothing was left of the noise
absorbing material : no more than the hairdresser has to collect when I have
my hair cut!
