Good Fortune!

I put the smoother side towards the pipe's flange but probably works either way.

I think z1 sells the Suzuki ones, which are slightly thicker. They should work if your exhaust system flanges are different from stock ones.

I put the smooth side toward the pipe flange........ can be used either way though ...... :huh:
