Aftermarket Exhaust Systems are a popular addition to any 2003-2004 Dodge 5.9L Diesel. A performance exhaust kit will typically add horsepower/torque, decrease the exhaust gas temperatures (EGT's), and can even help engine efficiency. Different diameter exhausts are available such as 4" & 5" and offer unique sounds for your vehicle. Exhaust installation is normally a do-it-yourself project that can be completed in your driveway. When you start shopping for an exhaust, a range of construction options and price points will become apparent. Exhaust Systems are typically offered in stainless steel and aluminized steel for your preference on budget, and application. All of the top manufacturers, including MBRP, Magnaflow, AFE, Banks Power, AP Emission Technologies, and more, are available today!
