Description
Overview
The Flowmaster Jeep (3.6) Exhaust System Kit is a Force II series stainless steel cat-back exhaust system engineered for the 2011-2022 Jeep Grand Cherokee (2022 Grand Cherokee WK only) equipped with the 3.6-liter V6. Built to deliver a stronger, more purposeful tone alongside real performance gains, this catback exhaust replaces the restrictive factory piping with mandrel-bent 409 stainless steel tubing for maximum exhaust flow and long-term durability. If you’ve been searching to shop for exhaust upgrades that balance sound, power, and easy fitment, this Flowmaster performance exhaust system checks every box.
Sound & Performance
At the heart of the system is a Super 50 series muffler that produces a moderate to mild sound level — assertive under throttle without droning on the highway. Tuned resonators (6.00″ wide x 3.00″ tall x 16.10″ long on both the front left and front right) further refine the note and help keep interior cabin volume comfortable for daily driving. On the dyno, this exhaust system delivers max gains of 11 horsepower and 15 lb-ft of torque at the rear wheels, so you feel the improvement in both power and character.
Build & Design
Every component is designed to work together as a complete car exhaust upgrade. The mandrel-bent 409 stainless steel construction smooths out flow and resists corrosion, while the 2.50″ inlet diameter and offset muffler inlet are matched to the 23.44″ overall length Super 50 muffler with a 2.50″ outlet. The system finishes with a large 4.00-inch polished stainless steel tip that carries an embossed logo for a clean, custom look. The silver pipe finish and black muffler give the setup a factory-plus appearance under the rear of your Grand Cherokee.
