I used it as a silencer gasket for CRM250AR. It's not on the fitment chart, but the length and diameter of the Silencer and Chamber sides are Exactly the same, so I thought there would be no problem. I also used a liquid gasket. So far there is no exhaust leak.
Purchased in preparation for Exhaust System replacement
We will be replacing the Exhaust System on the NINJA1000 soon! Naturally, I had to replace the Gasket, so I purchased it in preparation. Since NINJA's exhaust system is a dual exhaust system, two Gaskets are required. Gasket itself could have been anything, but I chose this one because it seems to be a standard product used by many people. I can't wait to replace it.
I bought it because I needed it to return to Normal muffler for car inspection. I am satisfied with the Gasket which seems to be a good seal in a firm shape, but I think that it is good if it is a little cheaper because it is a thing which cannot be reused.
