The MACH Force XP cat-back exhaust system for the Jeep Grand Cherokee SRT/SRT8 with the V8-6.4L HEMI or V8-6.2L (sc) HEMI 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. Muffler finish may vary.

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

ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
