Hey guys, I bought a used XB12S that has a K&N filter w open air box, and some exhaust mods. I'm just trying to identify what muffler is on this thing, and if it is set up correctly. The exhaust flap actuator is gone, and the PO fixed the cable so that the exhaust valve is maybe 50-75% open. If I try to rotate the exhaust valve by hand, it still moves a bunch. Should it be open all the way? I searched this forum but couldn't find anything relating to this or any pics of a muffler like mine. Here is a pic of the muffler. From what I can see inside, the last 12" or so it is just an open chamber with a metal grating around the inside of it. Also the tip is oval and it points straight at the rear tire, which seems weird. Check out the attached pic. Thx!
