Which Silencers?

I've currently got a set of the Norman Hyde pipes on my 2012 Bonnie and the bike has been set up to run these but I'm getting pretty fed up with trying to keep rust at bay on them so I might change. Anyone got any recommendations for some fairly cheap silencers that would work and sound ok? Also has anyone ever tried short reverse cone megas and does the bike run ok on those? Only asking there as I have a set in a cupboard that were only ever run for about a mile on my old Guzzi California, the bike ran fine but it really was deafeningly loud!
