    Hello everybody,

    I would like to replace the original muffler by the one on the pictures (link below).

    It’s a shorter model, it’s not only a tube. It has a silencer made by a short drilled tube inside.

    The question is simple : is it dangerous for the valves to put this item ? Some people said to me that I will burn my valves.

    But the Pilen has a decat followed by a primary silencer, then the muffler…

    I hope that a experimented technician could advice me on that.
