Question What are these ?

After putting new pipes on the VN and then taking them off, I found these bits at the bottom of the header pipe. There kinda of soft aliminium feel.

WTF?

Well you have heard of gall-stones and kidney-stones right?

Those are header-stones.

What type of crush gasket was installed? Just a wild guess, but the screaming eagle gaskets are a spongy material and that looks like something that could have burnt and fallen off the gasket.

Either that of maybe you had a mouse crawl up the exhaust and leave you a gift.

...Im tending to lean towards the crush gasket idea...the Harley ones I got look like a ring of compressed steel wool soaked in lead. I just replaced my old for new, and the old showed signs of melt where there was a slight leak.

Only thing is I only replaced the muffler , not the header and did not use a gasket, only the large outside harley clamp. B the way , these are great clamps, solid as a rock and good value at $9 AUD, $8 USD.

Maybe the crush gasket has split in side and they have rolled down the pipe.
