Force II Cat Back System; 2.5 in. Tubing; Dual Out Rear Exit; 409 Stainless Steel; 4.0 in. Polished
Flowmaster introduces our Force II stainless steel cat-back exhaust systems for the 2011-2021 Jeep Grand Cherokees with the 3.6 and 5.7-liter engines. These systems use a Super 50 series muffler 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. The systems use larger 4.00-inch polished stainless steel tips for a custom look. Max dyno gains of 11 hp and 15 lb-ft at the rear wheels with the 817628 kit. 817575 is a dual exit system that fits both 3.6 and 5.7-liter models with dual bumper cutouts. 817628 is a single exit system for 3.6-liter models only with a single bumper cutout. All of the necessary hardware is included, and factory-mounting locations are used for an easy installation. Backed by Flowmaster’s Lifetime Limited Warranty.
