Anyone know what gains can be expected from fitting low restriction mufflers to a standard XR8 exhaust system, or a combination of resonator replacing the centre muffler and sports rear muffler?

I want to know the same thing. There are heaps of threads on full systems but as for just the muffler, I havent come accross much.
