Ok cool . glad it might have been able to help.
Honestly. here is my thoughts on the exhaust. If your going to spend money to modify the exhaust just to pull the res section out. Your never going to be happy as there are so many crinks and bends that make the OEM exhaust restrictive and sound wise too tame,
If you can afford it I would suggest the JHM exhaust as its a really nice piece with no drone and a great tone. Lots of the issues you might run into building your own exhaust have already been worked out. But still if y ou can build your own exhaust or have one built it makes sense to spend the money on something your going to really want than to spend money trying to modify the exhaust to be better but still not what you really want.
