Flowmaster introduces our Force II stainless steel cat-back exhaust system for the 2011-2021 Jeep Grand Cherokees with the 3.6 and 5.7-liter engines. This system uses Super 50 series mufflers for a moderate to mild sound level and increased performance. Tuned resonators help keep the interior sound level low for a comfortable ride. Mandrel bent 409 stainless steel tubing allows for maximum exhaust flow and durability. A Scavenger X-pipe is used to increase torque and help control interior sound. This system uses larger 4.00-inch polished stainless steel tips for a custom look. All of the necessary hardware is included, and factory-mounting locations are used for an easy installation. Backed by Flowmaster's Lifetime Limited Warranty.
