Product Description

The Borla 140633CB ATAK Cat-Back Exhaust is engineered specifically for the 2015-2021 Jeep Grand Cherokee SRT equipped with the 6.4 L Hemi V8 and AWD. Featuring high-grade T-304 stainless steel, full 2.75" mandrel-bent tubing and an X-pipe design, it enhances both performance and sound. The dual 5" ceramic-black tips deliver an aggressive aesthetic while the ASA-tuned note amplifies the driving experience without compromising fitment or clearance.

Installation is bolt-on and straightforward--replacing the factory rear exhaust section with this system retains the hangers and flanges for clean fitment. With the ATAK system you get a significant upgrade in sound and flow; if a milder tone is preferred, the optional resonator kit converts it to the quieter S-Type level. Covered by Borla's Million-Mile warranty, the 140633CB stands as one of the premium exhaust upgrades for Jeep SRT owners focused on performance, sound and durability.
