    Careful doing it on a Kawi Exhaust systems as the walls are thin and the metal is soft. Often blows thru the inner liner and into the water jacket.

    Abrasive clay like material that is pressed under pressure through parts to polish them.

    For me, absolutely no gains in that part. Nothing on data logging either.

    Extrude has been around for a long time and does yield benefits on the 15F kits.
    I have yet to do it on the Ultra exhuast, call me chicken but I was spooked when a friend went through a couple of them getting it right.
