I'm going to preface this with the fact that this is only OEM exhaust system I have experienced this with. Many aftermarket mufflers (like Magnaflow) have a break-in period during which they get louder. My Charger had "Active Exhaust", which meant that it had flaps in the exhaust that opened, changing the tone, when you "got on it" or put it in Sport mode. The Jeep does not have this. I'm coming up on 40,000Km on the Jeep now and the exhaust is most definitely significantly throatier than in the past. It has a more noticeable bark and just in general, is louder than it has been. I mentioned it to my buddy that owns the dealership and he's observed the same thing with his TrackHawk I'm wondering if this is a GC or a GC SRT thing? Anybody with a 5.7 notice this happening? It doesn't bother me, as I have had some pretty loud cars, but I could see somebody coming from a Benz or Bimmer (my M5 was deathly quiet) perhaps finding it a bit obnoxious perhaps.
