silverwing 600 muffler gasket

hello all
i own a 2009 silverwing 600 my graphite muffler gasket is worn out in fact 80% of it is missing and needs to be changed
i have ordered one online with part number 18391-ML8-000
but when it arrived it appeared to be very small in size my muffler is much bigger it cannot fit so i searched everywhere for another one and i couldn't find a different one ...
is there any trims with different parts
can anybody help me out finding the right part to order
thank you




hint: picture 1 shows the part
       picture 2 is part number 12

18391-ML8-000 is definitely the right part number, and looks to be correct across all years.

Maybe you've been sent the wrong part?

Is it the inside diameter that appears too small bud ? If so take a small file to the header pipe, file gently until you get it back to steel, these seals have a habit of 'bonding' themselves in place.

I always carried one of the gaskets/packings with me---they are another items shops do not carry in stock. Of course bike runs without the gasket and probably with no harm---but the noise on long ride can drive you nuts!

I recently fitted one of these. I found it a tight fit but a little brute force helped it on.

Mine did appear 'slightly' too small at the inside diameter and removing the remains of the old one took a while, I think it was this which made the gasket appear too small. I'm sure you have the correct part.

i have removed the muffler and taken some measurements using a caliper ..the outer diameter of my exhaust pipe is 43mm that's what the inner diameter of the gasket should be ....the inner diameter of my muffler (outer diameter of gasket) is 49mm so 18391-ML8-000 is definitely not the correct part and is very smaller in size

Try your Honda dealer and let them figure it out.

Hmmm, a quick search on 18391-ML8-000 shows ...........

Genuine Honda exhaust gasket. This exhaust gasket was used on the header pipe #1 and #3 where they insert into the collector box on the CB400F. Avoid exhaust leaks due to old gaskets!  


***Note these Dimensions: I.D. - 31.9mm / O.D. = 37.3mm / Width 25.4mm

How did you go about removing the old gasket?
