Overview:
Flowmaster introduces our American Thunder stainless steel cat-back exhaust system for the 2018-2024 Dodge Durango with the 6.4-liter engine. This system uses Super 44 series mufflers for an aggressive to moderate sound level and increased performance. Mandrel bent 3.00-inch 409 stainless steel tubing allows for maximum exhaust flow and durability. The system uses larger 4.00-inch polished stainless steel tips for a custom look. This system also has tuned resonators to control interior sound and maintain driving comfort. Max dyno gains of 12 hp and 20 lb-ft at the rear wheels over stock. All of the necessary hardware is included, and factory-mounting locations are used for an easy installation. Backed by Flowmaster's Lifetime Limited Warranty.
