Borla Touring Cat-Back Exhaust System with 4-Inch Polished Tips (140406) - 2011-2021 Jeep Grand Cherokee 5.7L Hemi V8
Wake up the high-performance spirit of your SUV with the high-impact Borla Touring Cat-Back Exhaust System. Custom-engineered for 2011 to 2021 Jeep Grand Cherokee models, this premium full-length exhaust upgrade introduces Borla's legendary acoustic profile: the mellow Touring sound level. Formulated explicitly for driving enthusiasts and SUV purists who crave a highly sophisticated, deep exhaust note under acceleration without excessive volume, this system is calibrated to give the 5.7L Hemi V8 engine a bold, crisp, and high-impact growl. This configuration delivers a commanding exterior acoustic presence while relying on advanced straight-through internals backed by Borla's official No-Drone Guarantee to keep the cabin completely comfortable and drone-free during highway cruising, daily commuting, or heavy towing.
The internal engineering of the Borla 140406 targets key factory flow restrictions by incorporating an upgraded high-efficiency performance layout featuring a 2.5-inch diameter main pipe configuration. This performance architecture integrates a dedicated precision-manufactured Merge X-Pipe that balances exhaust pulses between cylinder banks, maximizes exhaust velocity, and optimizes scavenging to unlock hidden horsepower, sharper throttle response, and enhanced fuel economy across the entire powerband. Designed to route flawlessly along the undercarriage, it leaves plenty of extra flow capacity for additional aftermarket performance modifications down the road and is verified fully compatible with factory under-body armor and skid plates. Built completely from premium-grade, aircraft-quality T-304 austenitic stainless steel, this highly durable cat-back assembly defends permanently against structural degradation, intense under-car heat cycling, and severe corrosion. The spent exhaust gases exit through a clean single split rear configuration featuring dual 4-inch round, rolled edge angle-cut lined polished T-304 stainless steel tips mounted on each muffler. Precision CNC-manufactured for an accurate line-to-line bolt-on fitment, this system utilizes all factory mounting positions and is backed by Borla’s legendary lifetime Million-Mile Warranty.
Chassis & Configuration Notes: This cat-back system is engineered specifically for the 2-Wheel Drive (2WD) and 4-Wheel Drive (4WD) automatic transmission configurations of the WK2 platform Jeep Grand Cherokee equipped with the 5.7L V8 engine. It delivers a direct fitment for Limited, Overland, and Trailhawk trim levels. Please note that this assembly fits models with standard bumper configurations and is designed strictly to exclude vehicles equipped with integrated, reusable factory exhaust tips that are built directly into the rear bumper fascia.
