Hi folks, Im new to this forum, been on Dodgetalk for years. This is my third Ram Hemi, Had an 04, an 08 and now my 14 Crew Cab 4x4 Sport in Bright Silver. This truck is amazing compared to my others. I have a question as I begin to gather mods for install. I already orer the weather tech digital liners, and the Bakflip VP tonneau cover. I began to research cat back exhausts and discovered that the Sport is listed as having an aggressive exhaust in the manual. Does anyone know what muffler is on the sport, and is it different than whats on the SLT's, Expresses, and Laramies?
