Exhaust sys
Jacques, i think there are several muffler systems that would be seen
as production original on the Miura series. They all mount on the
header pipes in similar fashion. The earliest systems had small
mufflers usually round cans, but in later (early cars) these cans could
be oval. Usually had the cone section expansion chambers.
As time progressed, i guess ANSA became more sophisticated in
production, Miura owners wanted a little more quiet, so the mufflers
became slash cut style to fill all available space and became larger as
well. I am guessing to avoid the cost of the custom cone sections, the
units were fitted with the round end flares, also wrinkle black paint,
red inside pipes is seen on replacement systems sold at a dealer. here
is a drawing and picture of the earliest system type and the last SV
style.
the later systems , altho attractive, have a serious mismatch problem
with tail pipe to tail pipe, leading to Louisiana blackened Cajun rear
ends.
