O.K. My exhaust guy must think I am an idiot! I had him cut the resonators off and install straight pipe in their place.Result,nice sound but BIG DRONE inside at highway speeds.I then had him add two small "glasspacks" just behind the stock muffler.Less sound,same drone just at the speed where you like to travel the interstate.CRAP!!! I thought it would help iif he added an "H" pipe to balance things behind the two small glasspacks.YEP,DRONE BIG TIME.I can't take this on a brand new Grand Cherokee.What next? Go back to stock? Replace the resonators and try a couple of performance mufflers in it's place?My exhaust system looks like something not nice.I'm trying to laugh here but I am getting discouraged.Anybody try something else and have good results?
