WTB 2001 Honda CBR 600 F4i - Exhaust Muffler Gasket
 

My stock exhaust was taken from my bike so I have just the header to work with. I have since gotten a shorty exhaust, but I think I still need the exhaust gasket/sleeve that goes on the end of the header pipe where the slip on is clamped to.

Does anyone have an extra exhaust gasket they want to part with? I have the 2 seat 2001 F4i (not sure if it makes a difference).

I'm pretty sure the part # I need is: 18391-ML0-003

If someone has one, could you measure the inside diameter of this gasket and also the thickness of the gasket (or the outside diameter would work)? My exhaust pipe measures 1.875" (1 7/8") outside to outside and the shorty muffler I have measures 2.125" (2 1/8") inside to inside.

Thanks for your help!
