Borla S-Type Climber / Rock Crawler Cat-Back Exhaust System with Single Turn-Down Tip (140861) - 2018-2026 Jeep Wrangler JL 2.0L 4-Cylinder Turbo 2-Door
Wake up the high-performance spirit of your off-road rig with the high-impact Borla S-Type Climber and Rock Crawler Cat-Back Exhaust System. Custom-engineered for 2018 to 2026 Jeep Wrangler JL (2-door) models equipped with the 2.0L 4-cylinder Turbo engine, this premium exhaust upgrade introduces Borla's legendary acoustic profile: the classic S-Type sound level. Formulated explicitly for driving enthusiasts and off-road purists who crave an aggressive, sport-tuned exhaust note under acceleration, this system provides an assertive growl while conquering the trails. 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 daily driving, highway cruising, or intense trail navigation.
The internal engineering of the Borla 140861 targets key factory flow restrictions by incorporating an upgraded high-efficiency performance layout featuring an enlarged 2.75-inch pipe diameter that maintains optimal velocity. This specialized high-clearance 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. 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 trail conditions. The spent exhaust gases exit through a hidden single turn-down tip layout finished with a 2.75-inch brushed T-304 stainless steel pipe exiting at the left-rear location. Precision CNC-manufactured for an accurate line-to-line bolt-on fitment, this system utilizes existing factory mounting positions and is backed by Borla’s legendary lifetime Million-Mile Warranty.
High-Clearance Off-Road Architecture Notes: Designed specifically with total ground clearance in mind, this Climber and Rock Crawler configuration completely deletes the low-hanging rear muffler box found on factory setups. By introducing a high-tuck pipe layout that terminates before the bumper with a brushed turn-down tip, it drastically improves your Jeep's departure angles and maximizes underbody ground clearance to prevent hang-ups on jagged rocks, steep ledges, and deep trail obstacles.
