Think my exhaust might be a bit too loud, ( though not measured noise yet ). If I need to quieten it the usual way seems to be poke a core plug half way up the straight through silencer. Would making a cone to push in be better for flow or not worth the effort ?
Suppose I could just buy a pair of silencers, but where is the fun in that ?
