Borla S-Type Cat-Back Exhaust System with 4-Inch Polished Tips (140748) - 2014-2021 Jeep Grand Cherokee WK2 3.6L V6
Wake up the high-performance spirit of your SUV with the high-impact Borla S-Type Cat-Back Exhaust System. Custom-engineered for 2014 to 2021 Jeep Grand Cherokee 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 3.6L Pentastar V6 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 140748 targets key factory flow restrictions by incorporating an upgraded high-efficiency performance layout featuring 2.5-inch mandrel-bent tubing. This performance architecture utilizes ultra-smooth mandrel bends and patented multi-core internal geometry that 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 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. The spent exhaust gases exit through a distinctive truck single right rear exit configuration finished with a premium 4-inch round, rolled edge angle-cut lined bright chrome polished T-304 stainless steel tip. 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.
Chassis & Configuration Notes: This performance cat-back system is engineered specifically for the WK2 generation 4-door SUV models running the naturally aspirated 3.6L V6 engine paired with an automatic transmission. It provides complete structural underbody clearance and is fully compatible with both 2-Wheel Drive (2WD) and All-Wheel Drive / 4-Wheel Drive (AWD / 4WD) drivetrain layouts.
