Borla Touring Cat-Back Exhaust System with Single Square Polished Phantom Tip (14728) - 1997-1999 Jeep Wrangler TJ 2.5L 4-Cylinder & 4.0L 6-Cylinder
Wake up the high-performance spirit of your classic off-road machine with the high-impact Borla Touring Cat-Back Exhaust System. Custom-engineered for 1997 to 1999 Jeep Wrangler TJ models equipped with either the fuel-efficient 2.5L 4-cylinder or the legendary 4.0L inline 6-cylinder engine, this premium exhaust upgrade introduces Borla's refined acoustic profile: the mellow Touring sound level. Formulated explicitly for driving enthusiasts and trail purists who crave an upgraded, sport-tuned exhaust note without overwhelming volume, this system is calibrated to give the early TJ platform a clean, deep tone. This configuration delivers a throatier 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, open-air trail riding, or daily commuting.
The internal engineering of the Borla 14728 targets key factory flow restrictions by incorporating an upgraded high-efficiency single performance layout. The design features a smooth, continuous 2.25-inch mandrel-bent pipeline setup throughout the entire assembly to optimize structural routing under the TJ chassis and maximize exhaust gas velocity. At its core, this assembly features Borla's patented straight-through multi-core muffler technology, which increases scavenging efficiency to unlock hidden horsepower, sharper throttle response, and enhanced power delivery. 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 mud or trail debris. 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.
Polished Phantom Square Tip Styling: This premium single-exit kit terminates at the right rear passenger side with an eye-catching 3.38-inch by 3-inch rectangular/square angle-cut polished T-304 stainless steel "Phantom" exhaust tip. This specialized tip configuration provides a sharp, customized accent beneath the classic body lines of your Wrangler TJ, making it a perfect upgrade for drivers seeking a distinct, high-quality finishing touch.
Important Rear Trailer Hitch Fitment Restriction: Please note that this specific exhaust configuration is designed and clearanced exclusively for vehicles without a rear trailer hitch installed. Due to the precision routing of the 2.25-inch tailpipe and the larger profile of the square Phantom tip, this kit will NOT fit or clear vehicles equipped with a factory or aftermarket rear receiver trailer hitch.
