Flowmaster introduces the new American Thunder stainless steel cat-back exhaust system for the 2012-2021 Jeep Grand Cherokee that are fitted with the 6.4L Hemi V8. This system uses Super 44 series mufflers and tuned resonators for an aggressive to moderate sound level and increased performance. Mandrel bent 3.0-inch 409 stainless steel tubing allows for maximum exhaust flow and durability. The system uses larger 4.0-inch polished stainless steel tips for a custom look. Maximum dyno gains of six horsepower and 9 lb-ft of torque at the rear wheels over stock. All of the necessary hardware is included, and factory mounting locations are used for an easy installation.
