Borla S-Type High-Clearance Climber Cat-Back Exhaust System with Turn-Down Tip (140634) - 2012-2018 Jeep Wrangler JKU 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 2012 to 2018 Jeep Wrangler JKU (4-door) 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 bring out a deep, trail-ready tone from the 3.6L Pentastar V6 engine. 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 technical trail runs.
Engineered as a specialized High-Clearance Climber and Rock Crawler configuration, the Borla 140634 targets key factory flow and clearance boundaries. The system features a dual 2-inch into single 2.5-inch mandrel-bent layout that completely eliminates the bulky, vulnerable rear-most factory muffler. By rerouting the system to tuck safely above the frame rails and finishing it with a 2.5-inch brushed T-304 stainless steel turn-down pipe right after the axle, this system dramatically increases your rear departure angle and frees up valuable underbody space for aftermarket suspension upgrades, body armor, or rear-mounted accessories. To maximize space and flow under the front of the vehicle, the kit includes a built-in exhaust loop delete Y-pipe. This performance architecture optimizes exhaust velocity and scavenging to unlock hidden horsepower, sharper throttle response, and enhanced fuel economy on and off the trail. Built completely from premium-grade, aircraft-quality T-304 austenitic stainless steel, this highly durable cat-back assembly defends permanently against structural degradation, intense off-road impacts, heat cycling, and severe corrosion. Precision computer numerical control (CNC) manufacturing ensures an accurate layout, all backed by Borla’s legendary lifetime Million-Mile Warranty.
Emissions & Warranty Compliance: The integrated exhaust loop delete Y-pipe is engineered to allow your factory catalytic converters to remain completely untouched. This ensures the system stays EPA and CARB emissions legal while keeping your factory vehicle warranty intact.
Installation Notes: This specialized high-clearance off-road system requires cutting the factory original equipment (O.E.) system for installation, specifically along the driver's side exhaust pipe. Fitment is fully confirmed on Sport, Sahara, and Rubicon sub-models.
