Had a custom Borla 2.5 inch cat back exhaust put on my wife's 2015 Overland V6 today. Removed front muffler and replaced it with magnaflow X-pipe. Then removed both rear resonators and replaced with Borla Pro XS mufflers with 4 inch stainless tips. It sounds awesome. Nice deep tone with no drone at any speed. Video makes it sound Raspy but in person it sounds great.
