Ec flattracker, if you  have not started cutting the mid pipe already  i can take pictures  of how the mid pipe sits on my Aaen, mine  fit exactly like yours when i got it but all i did was  removed about 1 inch max. off the front pipe collar which was about 3-4 inches long. Doing that changed the angle of how the silencer lined up at the back. Than i used a step drill bit and made the holes much larger and fit rubber grommets inside and between the tabs and frame. You will need to beef up the tab welds at silencer or they will brake off if you plan on ridding rough trails.
