I currently have the short TOR's on my BA 2004 but these are straight through and consequently get a lot of popping on deceleration . They are quite loud so have to go easy in built up areas. These sound like the Triumph Scrambler , and am now considering the D&D megaphones , as I used to have reverse cone megas on my old T110 all those years ago.
I have heard that some versions of the short TORs are not straight through and these would be too quiet for me.
But they look good!!
