Performance exhaust systems come in various sizes. The most prevalent is the four-inch system, suitable for vehicles generating under 450 horsepower. For higher-powered vehicles, larger diameter exhaust systems like the five-inch are recommended. These systems enhance exhaust flow by replacing the stock muffler, using smooth mandrel bent tubing, and increasing pipe diameter. The advantages include lower EGTs, improved horsepower and torque, better fuel efficiency, and a deep, resonant exhaust note.
