Let's start flaming!!
The system on my Spitfire is similiar (all though larger diameter) to the
sports type exhaust originally used by the factory, and supplied by
TriumphTune in the UK to this day.
The difference is that you can use 2 relatively low cost mufflers, rather
than one very expensive single (which is normally required to acheive the
"low restriction").
My two cents worth, and I can tell you from experience that it is a major
step up from the earlier single exhaust.
