Speedmaster Silencer Help

Hello Triumph people.
Can you help me with Speedmaster silencer? My Speedmaster 2003 silencers are too loud, because previous owner removed some baffles (half of the pipe is emty). I found used silencers from webshop, but I`m not sure, does it fit to my 2003 year model. Silencer model in webshop is 2206412.

 

Thanks, Joe. Not sure what you meant by "But quickly pull the one on there of a and give it a go not that big of a job."
Silencers are in Lithuania. Can`t try them before I buy.
