Borla offers two options for the V8 Camaro. The "S" Type, or Stinger, is the more aggressive of the two options. The touring version is a more mild mannered exhaust note. Each Cat-back system includes an x-pipe, mufflers, and all necessary hardware for installation. These systems will also provide an increase in HP due to the better flowing properties of this system compared to the stock exhaust piping. 140331
