Why is there 2 different exhausts on my U/C
Left Side Pt# 65538-07
Right Side Pt# 65846-07
But both have HARFLT 1584/1688 I think from surfing the web I found out these 2 #'s mean 96 ci and 103 ci
If any 1 could give me anymore info it would be greatly appreciated

Thanx

 

I'm not sure about your '07, but the ones on my '09 have indentations on the inside for the axle nut or lower shock nut and that makes them side specific.

 

They are different on the outside and on the inside on my 08. I think the rt side has a cat.

 

I don't think there are any catalytic converters in the mufflers. They are in the head pipes and only in '09 CVO's and then in all bikes starting in the 2010 models.

I believe that not only are the mufflers different on the outside for left and right, but also on the inside as there is more flow to baffle on the right side as compared to the left.

 

The left side does not have as much output, there will be a smaller diameter core in the left, and the right side will be slightly bigger.
