Borla S-Type Cat-Back Exhaust System with 5-Inch Polished Tips (140632) - 2015-2021 Jeep Grand Cherokee SRT 6.4L V8
Wake up the high-performance spirit of your SUV with the high-impact Borla S-Type Cat-Back Exhaust System. Custom-engineered for 2015 to 2021 Jeep Grand Cherokee SRT (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 high-output 6.4L 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 driving, or family road trips.
The internal engineering of the Borla 140632 targets key factory flow restrictions by incorporating an upgraded high-efficiency performance layout featuring a 2.75-inch mandrel-bent piping architecture. The system contains an integrated high-flow Merge X-Pipe that perfectly balances exhaust pulses for increased performance, maximum exhaust velocity, and a significantly improved acoustic profile. This design optimizes scavenging to unlock hidden horsepower, sharper throttle response, and enhanced fuel economy across the entire powerband. 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 split rear exit configuration finished with massive single 5-inch round, rolled edge angle-cut bright chrome polished T-304 stainless steel tips that fill out the factory rear valance beautifully. 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.
Modular Sound Customization: For drivers looking to shift to an even louder acoustic footprint later on, this versatile S-Type system features a modular architecture. You can easily utilize the optional Borla Resonator Kit (part number 60635) to convert this existing configuration directly into an ultra-aggressive ATAK sound level system without replacing the entire cat-back assembly.
Chassis & Configuration Notes: This performance cat-back system is engineered specifically for All-Wheel Drive (AWD) 4-door SUV body styles running the naturally aspirated 6.4L V8 engine choice paired with an automatic transmission. It utilizes factory hanger locations for a seamless installation.
