Upgrading my 14 Grand Cherokee Overland w/5.7, with a cold air intake and curious about mufflers. Will the SRT mufflers work, are they less restrictive or is it a waist of time. To many reviews complaining about drone noise with the catback systems. I also like the stock sound of mine and the SRT, plus I don't want to raise up the cabin noise. Any suggestions? I was also told that the systems computer will over ride an after market chip. Don't want a tuner.
