May 16, 20179 yr Hi Can anyone help me with information about the exhaust system on my 1980 RL250? I'm trying to find out if the main box has any sound reducing material inside or is it just an empty box? I have cut open the rear box and found evidence of some sound deadening material, so I will clean it up and re-pack it and weld it up. Regards Phil

May 17, 20179 yr Author For those who are interested the inside of a RL250 main box looks like this: http://i513.photobucket.com/albums/t336/philcbr/RL250%20stuff/DSCF2755_zps5mlqwzrg.jpg http://i513.photobucket.com/albums/t336/philcbr/RL250%20stuff/DSCF2759_zps66zpinn7.jpg Gave the inside a quick clean with a wire brush, looks ok. There is something behind the mesh which is hard enough to rattle, I’m guessing it is the remains of some sound absorbent material mixed with the oil which has formed a hard substance. Replacing the wadding? Will be difficult as the mesh is spot welded in place….more work. Phil
