Anybody know the difference between these two touring SE mufflers. One is for the 07-08 and the other is for 09-10. Both are one piece street performance mufflers, Part Number's 80491-07 and 80721-09 which look and cost the same. I have the 08 version and would like to put them on my on order Limited 2010 but I am concerned about the new part number.

 

My guess is that they aren't exactly the same, the mounts could be different due to the redesigned frame or the wider back tire. The insides could be different as well.
