Thanks for the help Anamoly, the only problem is that the hangers for the rear muffler section on my new exhaust will get in the way of placing the branch resonators behind the two rear mufflers. If they are mounted before the mufflers HKS style, would they still be effective?
Edit: here are some pictures of my setup, where would you recommend mounting the branch resonators? Note the exhaust hangers are sort of in the way behind the mufflers.
