Hello everyone! I purchased my 2013 Ram 1500 Laramie in October of last year and I truly love the truck. I've been reading posts like crazy for the last few months and have gotten some great info but this is my first post. I've really enjoyed the forum and it has been very helpful. I have several mods as you can see from my list. My biggest concern right now is an issue I'm having with my mopar catback. I love how it sounds when I get on the throttle, how it sounds at startup, and all that fun stuff. However, today I went on my first trip since having the catback installed in which speeds we regularly at or above 70mph and I noticed a severe drone in the cabin. Even when I was just cruising without accelerating it almost sounded as loud as if I was accelerating. This is my first exhaust system of this caliber and I'm not sure if this is normal but I felt like it was pretty bad. What are the solutions? I've been trying to look around and see what people have to say on the forum but it is hard to search through so many threads with other things being talked about in them. Here's what I've come across so far: use a mufflex drone suppression pipe, have the stock resonators put back on (I still have the original exhaust), turn of MDS for which I would need tuner and that would more than likely void my warranty. I want to keep that beautiful deep throaty sound because that was the whole point of the mod but lose the drone or at least reign it in because it was pretty bad. What is my best option here?

You dont need a tuner to turn off MDS. Manually put your truck into 6th or 8th gear and it will disengage MDS. The only downfall is you have to do that every time you move your truck from drive. It will still shift normal from stops. Hope this helps. I have the same problem with mine. I welded in a straight pipe and left both resignators. It sounds horrible when the MDS kicks in. Wish i didnt have it
