OK. So if the cats are the main restriction on the G8 then why not get a cat back system but use the stock mufflers to keep it quiet, and use the stock headers for the same reason. Any input would be appreciated.

cat-back leaves the restriction of the cats....
Thanks WreckWriter. Is there a way to modify your exhaust system the way I outlined above? Or would it not produce enough power increase to be worthwhile?
ARH and stock muffs will set you free and keep you smiling Bro!
