Borla S-Type 2.75-Inch Axle-Back Exhaust System with Polished Tips (11963) - 2018-2026 Jeep Wrangler JL & JLU 2.0L Turbo (Includes 4xe)
Wake up the adventure-ready spirit of your rig with the high-impact Borla S-Type Axle-Back Exhaust System. Custom-engineered for 2018 to 2026 Jeep Wrangler JL (2-Door) and JLU (4-Door) models powered by the modern 2.0L 4-Cylinder Turbocharged engine, this premium upgrade features Borla's legendary mid-level acoustic profile: the S-Type (Stinger). Strategically positioned right between the mellow Touring sound level and the race-inspired ATAK, the classic S-Type delivers a noticeably throatier, more responsive exhaust note and increased overall volume without ever becoming intrusive or fatiguing on daily drives. The advanced straight-through internal mufflers are acoustically tuned specifically for the 2.0L powerplant, and come backed by Borla's official No-Drone Guarantee to ensure your interior cabin remains quiet and comfortable during long highway cruising or open-air trail rides.
The internal engineering of the Borla 11963 targets key rear flow restrictions by replacing the restrictive factory rear muffler layout with a high-flow performance configuration. It features a robust 2.75-inch inlet diameter feeding into the core assembly and splitting into smooth, dual 2.5-inch mandrel-bent tailpipes out. Built completely from premium-grade, aircraft-quality T-304 austenitic stainless steel, this durable axle-back system smoothly accelerates gas velocity, optimizes exhaust flow, and provides permanent defense against harsh off-road mud, road salt, and rust corrosion. The spent exhaust gases exit through a sporty dual split rear layout featuring two 3.5-inch round, rolled angle-cut lined mirror-polished T-304 stainless steel tips (one on each tailpipe) that neatly frame the lower rear bumper lines. Precision CNC-manufactured in the USA for an accurate line-to-line bolt-on fit, this high-performance upgrade is backed by Borla’s legendary lifetime Million-Mile Warranty.
Chassis, Powertrain, & 4xe Hybrid Notes: This versatile axle-back system fits standard 2-door (JL) and 4-door (JLU) Wrangler models equipped with 2-wheel or 4-wheel drive and the 2.0L Turbo engine. It features extensive engineering coverage that includes **Wrangler 4xe Plug-In Hybrid models**, ensuring proper clearance around hybrid battery configurations and chassis crossmembers. It installs as a straightforward, direct bolt-on replacement for the original equipment rear muffler assembly using factory hanger locations.
