muffler for a 2015 Ram 1500 5.7L V8 Hemi. If you're like me and NOT looking forward to the silent world of autonomous electric vehicles, then this muffler is for you. If you are a car enthusiast, this will definitely put a smile on your face. Loud enough to be noticed but not loud enough to annoy the neighbors too much. I just replaced the stock muffler. NOTE: If you are doing your own work, you will need to add a 3" pipe on the inlet side to accommodate the difference in length between Super44 and standard (standard is much larger). You will also need to make hangers to ensure they fit the existing supports on the undercarriage. If your local shop does all the work for you, they will take care of everything.
