i got that megaphone from retrorocket,its an old transac,the headers might be yoshi copies?i made up a nice long baffle and end cap for it,its straight through but not loud,i want to make a reverse cone end cap for it,with wide open its droney,its better with the reduced outlet but im not keen on the square edged outlet.
thats an engine water pump pulley with the vee drive cut off it,fluke size.
i found this the other day in a skip bin,im toying with it still,i like the transac though.
pro circuit titanium,i peeled all the scuffed up decals from it already.
