Do you think , it has a big difference , for engine performance , between exhaust pipe from square noze and round noze ? between 50 mm and
60 mm ?

There is no difference after the waterbox. One of the strongest running skis in our group had a kink in the long hose.

Hmm, not sure i agree with this - a kink will lead to gas finding it harder to get out = increased temps back into motor

pipe size reduced is one thing, a kink is second thing .....
