Borla S-Type Cat-Back Exhaust System with 5-Inch Polished Tips (140245) - 2006-2010 Jeep Grand Cherokee SRT8 6.1L V8
Wake up the high-performance spirit of your track-ready rig with the high-impact Borla S-Type Cat-Back Exhaust System. Custom-engineered exclusively for 2006 to 2010 Jeep Grand Cherokee SRT8 (WK) 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 SRT purists who crave a highly aggressive, race-inspired exhaust note under acceleration, this system is calibrated to give the high-output 6.1L 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 spirited track runs.
The internal engineering of the Borla 140245 targets key factory flow restrictions by incorporating an upgraded high-efficiency performance layout featuring a large dual 2.75-inch main pipe diameter. This performance architecture utilizes ultra-smooth mandrel bends and a straight-through multi-core muffler configuration that maximizes exhaust velocity to unlock hidden horsepower, sharper throttle response, and enhanced fuel economy across the entire powerband. Designed to support the high-breathing demands of the naturally aspirated 6.1L power plant, it leaves plenty of extra flow capacity for additional aftermarket performance modifications down the road. 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 the iconic, signature SRT8 dual center rear configuration featuring massive 5-inch round, rolled edge angle-cut long mirror-polished T-304 stainless steel tips. 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 first-generation high-performance WK Grand Cherokee SRT8 platform powered by the 6.1L Hemi V8 engine. It is fully compatible with the factory 5-speed Automatic transmission and fits 4-Door Sport Utility Vehicle (SUV) All-Wheel Drive (AWD) models. It is designed exclusively to mate with the unique central bumper valance assembly layout of the SRT8 and will not fit standard 3.7L, 4.7L, or 5.7L Grand Cherokee models without extensive rear fascia and mid-pipe modifications.
