Borla S-Type Cat-Back Exhaust System - Uses Factory Tips (140755) - 2018-2021 Jeep Grand Cherokee Trackhawk WK2 6.2L Supercharged V8
Wake up the high-performance spirit of your SUV with the high-impact Borla S-Type Cat-Back Exhaust System. Custom-engineered for 2018 to 2021 Jeep Grand Cherokee Trackhawk WK2 models, this premium full-length exhaust upgrade introduces Borla's legendary acoustic profile: the classic S-Type sound level. Formulated explicitly for driving enthusiasts and performance purists who crave an aggressive, sport-tuned exhaust note under acceleration, this system is calibrated to give the supercharged 6.2L Hellcat 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 driving, or family road trips.
The internal engineering of the Borla 140755 targets key factory flow restrictions by incorporating an upgraded high-efficiency performance layout featuring high-flow mandrel-bent tubing integrated with an advanced performance Merge X-Pipe. This performance architecture utilizes ultra-smooth mandrel bends and a precision-engineered center intersection that balances exhaust pulses, 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 clearance and is tailored exclusively to match the specific 4-door SUV Trackhawk body style. 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. Precision CNC-manufactured for an accurate line-to-line direct bolt-on fitment, this system utilizes all factory mounting positions for a straightforward installation, all backed by Borla’s legendary lifetime Million-Mile Warranty.
Tip Configuration & Integration: This system is engineered strictly to re-use your vehicle's original factory exhaust tips and does NOT include new tips in the box. This allows you to retain the stealthy original rear aesthetic while drastically increasing flow and sound. For owners looking to completely refresh their tailpipe appearance, optional replacement Borla tips are available and can be purchased separately.
Chassis & Configuration Notes: This performance cat-back system is engineered specifically for the WK2 generation 4-door Trackhawk SUV models running the supercharged 6.2L V8 engine paired with an automatic transmission and All-Wheel Drive (AWD).
