Aftermarket Exhaust Systems are one of the most popular modifications for any 2014-2018 Jeep Grand Cherokee 3.0L EcoDiesel. Exhaust systems are typically available in stainless or aluminized steel and are available in a wide range of diameters and styles. 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. Installation is typically a straight forward installation and can be completed in your driveway with simple hand tools. All of the top manufacturers, including MBRP, Magnaflow, AFE, Banks Power, AP Emission Technologies, and more, are available today!
