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. #140280
