I just purchased a 2014 GT and the exhaust is a little too loud for me, and there's also a rotten egg smell when I accelerate and also in the garage after driving. It's currently back at the dealer right now being inspected for an exhaust leak, but a mechanic friend of mine said it might also be tuned rich. From what the dealer said upon purchasing, it might have headers, but it has high flow cats and a Roush axle back exhaust (which I also had on my 17 GT).
If there's no exhaust leak, what would you guys suggest to make the car a little quieter? Would I be able to get away with keeping the headers and high flow cats, but getting a quieter axle back (maybe MBRP, Borla Touring)? Or would I definitely have to go to stock headers and cats?
Also, if there's no leak and it still smells like rotten eggs, would a retune fix that issue? I do have a local dyno tuner that I have gone to previously.
Thank you. Right now my plan is to make sure there are no exhaust leaks, switch to a quieter axle back, and get the car retuned. Would like to hear thoughts from you guys. Thanks!
