18- Durango SRT 6.2/6.4L Cat Back Exhaust Kit

The 2018 Durango SRT 6.2/6.4L cat back exhaust kit from MBRP delivers the aggressive sound and improved flow dynamics that tactical and law enforcement operators demand from their vehicles. Built for the modern Mopar Gen III Hemi platform, this system replaces the factory exhaust section from the catalytic converter rearward, allowing you to maintain OEM emissions compliance while unlocking the auditory and thermal signature your engine produces. Whether you're running fleet support, emergency response, or high-duty patrol cycles, a quality exhaust system reduces heat soak in the engine bay and improves reliability under sustained operational demands.

This cat-back exhaust kit features a 3-inch diameter tube design constructed from stainless steel tubing, engineered to resist corrosion and withstand the thermal stress of sustained high-RPM operation. The carbon fiber look tips provide a finished aesthetic while the natural stainless material underneath offers proven durability in field conditions. MBRP's design optimizes scavenging efficiency—the process by which exhaust gases exit the cylinder head—reducing back pressure and allowing the 6.2L and 6.4L Hemi engines to breathe more freely. This geometry directly improves throttle response and reduces under-hood temperatures, critical factors for vehicles operating in demanding environments or towing heavy loads.

This exhaust system is engineered specifically for the 2018–2023 Dodge Durango platform, ensuring precise fitment without modification or adapter plates. Installation requires removal of the OEM exhaust components and hanger placement; no cutting or welding is necessary on the vehicle frame. Law enforcement and military fleet managers benefit from standardized maintenance intervals and sourced replacement availability through tactical supply channels. The kit weighs 73.6 pounds and ships in a compact 16 x 14.5 x 47-inch package, making it suitable for centralized receiving and installation at depot or regional service facilities.
