I'd say you're right, looking closer it seems it's just an Arrow sticker, the can has a badge with Japanese on it. Better pictures:



It leaks from the join to the front headers below, and it may also leak from the join to the back headers, but it does not seem to leak where the can joins the pipe.

By the way, are the gaskets at the rear header flange the same as the ones for the exhaust flanges at the cylinders? I figure I should just replace them all.

clear silicon will help seal the joins, take the can off squeeze a smidge on and re insert can let it dry for a few hours before restarting.

All the gaskets are the same copper ring type except where the front headers join the system under the engine where they are a sleeve type but there normally only used on a standard system, after market systems like yours are just a straight fit with no gasket or maybe a bit of silicone if it blows.

Clear silicone won't last long with the heat. Better to use lead sheet sealant as that is designed to cope with heat.

been using it for years never had a problem, did it on my yamamota and my tyga, its still tight, and on other cars around the joints

Wurth sell it to garages, so its a trade thing i guess. silicon is made from silica which in short is glass/sand so is capable of handling heat to a certain extent

That's a suzuka nosecone & rc45 style seat unit.

& Rick is right, some silicone will work as exh gasket, I have loads of different types of sealant heat resistant, heat proof, marine & normal crap silicone thats no good for nothing.

I have 1 of those systems on my No3 bike, I have no idea what it is but is very well made & a good system. I quietened it down with a BS stamped road can but I went back to a race can, as it sounded better.
