The Borla ATAK axle-back system for the 2018-2026 Jeep Wrangler JL and JLU is a 2.5in diameter system tuned for the 3.6L V6. ATAK is the most aggressive of Borla's sound levels, delivering the loudest, most assertive tone while still carrying Borla's No-Drone guarantee. It features a single 3.5in round polished T-304 stainless steel tip on each tail pipe. Borla Cat-Back and Axle-Back systems use patented straight-through, multi-core technology to free up hidden horsepower, add exhaust velocity, and produce the distinctive Borla Sound of Power. Each system is built from premium T-304 stainless steel, with ultra-smooth mandrel bends and precision CNC manufacturing for maximum flow and an accurate bolt-on fit. This axle-back installs behind the factory catalytic converter and retains all factory emissions equipment. It is made in the USA and backed by Borla's Million-Mile Warranty.
