Aftermarket Exhaust Systems are a popular addition to any Gas Vehicle. Exhaust installation is normally a do-it-yourself project that can be completed in your driveway. When you start shopping for an exhaust you will notice multiple construction options and price ranges. Many manufacturers offer exhaust systems constructed in either aluminized steel or stainless steel. An aftermarket exhaust will typically add horsepower/torque, lower the exhaust gas temperatures (EGT's), and can also improve engine efficiency. Exhaust systems can be offered in either 4" or 5" diameters, depending on your needs and preference. You can find exhaust systems from all of the leading brands like MBRP, Magnaflow, AFE, Banks Power, AP Emission Technologies, and more!
