(last pipe) thats a Huge Header! what is the diameter in the beginning?

and almost no angle to it :?

further , it looks nice..

for how many cc is this exhaust?


better rezise the pics by the way..
 
Thats right the header looks very huge but the diameter at the beginning is 28mm. and he is conical. so angular.

the exhaust is for 70cc and the performance convinced

No, not yet.
in winter I will build exhaust systems for minarelli.

here i show two diagrams.
at the first one, I have tested the roost sprint hr exhaust against my prototype.

But the RPM were too high. So I have the exhaust pipe rebuilt again.
then the RPM were better and the torque was more. (I had accidentally deleted the roost diagram, so I could no longer curves of each other)

The variator has been blocked, while the engine lost power about 20%
The motor has about 24 hp with open Variator.
