AFE Mach Force Exhaust System

12-21 Jeep Grand Cherokee 6.4L SRT

49-48053

The MACH Force XP cat-back exhaust system for the vehicle engine offers a max gain of +21 HP 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 IN tubing which improves performance across the power band while maintaining a great tone and aggressive sound during shifting. This system also incorporates an equalizer balance tube to evenly distribute exhaust pulses throughout the exhaust system for more efficient flow and improved performance.

Aggressive Sound:
Dual free-flowing mufflers are used to absorb high pitch tones producing a powerful sound and unleashing all available horsepower and torque.

X-Pipe Balance Tube:
The equalizer balance tube evenly distributes exhaust pulses traveling through the exhaust system. This not only creates a more efficient flow and better performance, it also reduces decibels minimizing exhaust drone.

Simple Installation:
This is a direct bolt-on system that retains your factory exhaust tips and includes all necessary hardware for a hassle-free installation. No modifications necessary.

Leak-Free Seal:
High quality band clamps are used for a complete 360 degree sealing surface.

Emissions Disclaimer:
This product does not require a CARB EO#
