Getting the air in will give you more power. Getting the air out will give you more power. When you get more air in and out at the same time, you get a lot more power. With our 4 inch exhaust systems are mandrel bent aluminized steel which eliminates the sharp bends and kinks that the factory stock exhaust systems have. The aluminized steel resists corrosion as well as stainless steel but is priced more economically.
