I think two smaller down pipes of the same total area would be quieter.
Especially if they were square.

Hello everyone,

another one on the temps:

KELVIN:
Definition: Symbol K. The SI unit of thermodynamic temperature equal to the
fraction 1/273.16 of the thermodynamic temperature of the triple point of
water. The magnitude of the Kelvin is equal to that of the degree Celsius
but a temperature expressed in degrees Celsius is numerically equal to the
temperature in kelvins minus 273.15. The absolute zero of temperature has a
temperature 0 K (-273.15°C). The former name degree kelvin became obsolete
by international agreement in 1967 and the degree symbol (o) is no longer
used.
....(I have no idea what is a triple point...)
For a "All included" Conversiontable and/or Converter go to:
http://www.allmeasures.com  ....you find "Temperature" on the very top -
right hand - under "sections"

Why would square exhaust pipes be quieter than round ones?

Square exhaust pipes on rotaries were discovered by the Russians.
It breaks the sound up into more frequencies. I think. Maybe like
homogenizing it :)
