Description
Overview
The Flowmaster Force II Cat-Back Exhaust System is a complete, performance-minded upgrade engineered for the 2011-2021 Jeep Grand Cherokee equipped with the 3.6-liter or 5.7-liter engine. Built to deliver a smart balance of added flow, improved sound, and true bolt-on convenience, this Force II series system replaces the restrictive factory piping from the cat-back with mandrel-bent tubing and Flowmaster’s proven Super 50 series mufflers. The result is a moderate-to-mild exhaust note that sounds great outside the vehicle while keeping the cabin comfortable on long drives.
At the heart of the system are Super 50 series mufflers with an offset inlet and offset outlet, a 2.50-inch inlet and 2.50-inch outlet, and a 23.19-inch overall length. Tuned resonators are used to help keep interior sound levels low, so you get the deeper tone you want without the drone. A Scavenger X-pipe ties the system together to help increase torque and further control in-cabin sound.
Key Benefits
Every detail of the Force II is designed for durability and performance. Mandrel-bent 409 stainless steel tubing maximizes exhaust flow and stands up to the elements for the long haul, while the black-finish mufflers and silver piping give the underside a clean, purposeful look. Finishing the system are larger 4.00-inch polished stainless steel tips with an embossed logo for a custom appearance that lets everyone know your Grand Cherokee is running a genuine Flowmaster.
