It may be out of print now.I got a used one and put it on.
Cut the genuine center pipe, insert it, and tighten it with a band.
If it is simply a thick pipe, it will become empty, but it seems that the gradually thickening shape produces pulsation and speeds up the flow velocity.

LY's muffler is 2 pieces, but the length is not equal.
This part seems to be balanced by changing the thickness of the left and right.
Torque has been increased in the mid-range.
I can't try high revs because I'm afraid of losing my license points (*´꒳`*)
