Like this pic. HKS did this to the 350Z

Active Autowerke does something like this don't they? I was thinking of putting in resonators directly behind the mufflers..I have been thinking of taking off the stock resonators past the x pipe, putting in some more piping, and putting the new resonators further back, closer to the mufflers now. Would that make a difference? The setup like the HKS is very intriguing but may cause a headache for the muffler shop? Interesting, nonetheless!
