My 3.6 has headers, cat delete pipes and a GHL twin can muffler. Love the sound of the muffler but it is a little loud and does have drone at 2400 - 2800. I have been thinking about what to do as I don't want to quiet it down too much and don't want to add much weight. I finally decided to add two resonators ( one each side ) before the u-bends leading into the muffler. Took it to a local Porsche shop and they took some measurements and we're going with 12 " overall length Vibrant brand . They came in today I'm dropping off the car tomorrow morning. So I'll chime in tomorrow with the results but I think it will take off just enough edge/resonance to make my exhaust perfect.
