aFe is proud to announce the MACH Force XP cat-back exhaust system for the 2012-2017 Jeep Grand Cherokee SRT/SRT8 with the V8-6.4L HEMI engine. In recent testing, this system resulted in a max gain of an astounding +21horsepower and +35lbs. x ft. of torque as verified by our in house dyno. This exhaust system is constructed out of mandrel-bent stainless steel tubing for unrestricted flow and is MIG-welded for strength and durability. This system utilizes dual, high-flow mufflers with 3” tubing which improves performance across the power band while maintaining a great tone and aggressive sound during shifting. aFe also has incorporated an equalizer balance tube to evenly distribute exhaust pulses traveling through the exhaust system. This not only creates a more efficient flow and better performance but also reduces decibels minimizing exhaust drone. This is a direct bolt-on system which retains your factory exhaust tips and includes all necessary hardware for a hassle-free installation. No modifications necessary.
Dual free-flowing mufflers are used to absorb high pitch tones producing a powerful sound and unleashing all available horsepower and torque.
