I'm running a spare engine as a static engine.  I hope to fire this engine up regularly and keep it s a running spare.  YouTube video

The engine has standard header pipes and collector boxes but it's still going to be too loud and annoy the neighbours.

My question is: will putting baffles into the rear of the collector boxes silence it at all or do I need to get a silencer made up to fit? If so should I buy a bike rear silencer/muffler or can one be fabricated in some Heath Robinson way from an old paint or baked bean can or something?

Something like Ebay item 133671265314 will do it. (Unable to post Ebay link).
