		If you have a good tight fit between the collector box outlet pipe and your silencer pipe with the existing gasket in place- then fine.
For bolt sizes/part nos have a look at the Yamaha online parts catalogue. If you need a replacement gasket-I have a new one here-internal diameter 45mm external dia 50mm-this is the one to fit the standard OE Yamaha silencer/pipe. PM me if required Dave
