Living in the forest of tubing....
Dear sherwood,
the comparison was just to make clear what gas flow volume is taking its way through a relatively small tube without restricting and causing the loss of power and torque.
And this is a strong argument to be considered when choosing from all systems available, or getting something build custom made.
A smaller system with smaller diameter is generating more velocity and a stronger pulse at the joining spots.
Looking at what Porsche did on street and race cars is telling exactly the same story.
We are working on our dyno every day and see evidently what happens.
Very often we change systems or adapt headers that we fabricate to be fitted on existing mufflers / silencers and in a lot of cases we use smaller tubes, if necessary, and produce more power and torque on a wider range.
At the end of the day the surface size under the power and / or torque curves makes the fast engine; whether it is a street or a race engine.
I was writing the tube diameter is 45x1 mm so the inner diameter is 43 mm !
Remaining with best regards
Dirk
