MERCO ( earlier ones had a wierd strap )
one can file them , and chew the baffles out maybe . Like a OS Silentflow .
The gungeie std ST 46 / Como one bolts on . You can grind off the outside to save an ounce . Some cut the tail pipe off .
Theres a big fat sausage aft that bolts on too . Blocking its outlet and drilling ten 2 mm holes in three rows ( 4-3-4 0)
at about 5 mm spacing , in the side aft , works pretty good .There .
Any of the swing/swivle ST late ones fit , but a bit gruesome astheticcallly, however you pronounce it .
One or two of the big ugly japanese ones , of a chunder tigre 46 etc will just wince on . a mm out but grit the eyballs & it goes on .
Easiest'd be a toungue from Brodack . and lightest. or Randy .
Depends on the power trip you want . Airframe weight & climate . big or small outlet .
