Borla ATAK 2.5-Inch Axle-Back Exhaust System with Polished Square Tips (11860) - 2012-2018 Jeep Wrangler JK & JKU 3.6L V6
Wake up the adventure-ready spirit of your rig with the high-impact Borla ATAK Axle-Back Exhaust System. Custom-engineered for 2012 to 2018 Jeep Wrangler JK (2-Door) and JKU (4-Door) models powered by the versatile 3.6L Pentastar V6 engine, this premium upgrade introduces Borla's highest-decibel acoustic profile: ATAK (Acoustically Tuned Applied Kinetics). Formulated explicitly for driving enthusiasts who crave an uncompromising, race-inspired trail roar under acceleration, the ATAK multi-core mufflers target, balance, and focus natural sound waves. This creates a bold, aggressive exhaust signature on the exterior while utilizing advanced internal design to keep the cabin completely devoid of harsh resonance or drone during highway cruising or long overland expeditions.
The internal engineering of the Borla 11860 targets key rear restrictions by replacing the bulky factory muffler with a high-flow, mandrel-bent infrastructure featuring a 2.5-inch inlet diameter feeding into the muffler and splitting into dual 2-inch 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 defends permanently against harsh off-road mud, rust, or corrosion. The exhaust gases exit through an aggressive dual split rear layout featuring two unique 3.5-inch x 3.28-inch "square" rolled angle-cut lined bright chrome on T-304 stainless steel tips (one on each side) that add a distinct, rugged custom appearance to your rear bumper line. Precision CNC-manufactured for an accurate line-to-line bolt-on fit, this system is backed by Borla’s legendary lifetime Million-Mile Warranty.
Chassis & Configuration Notes: This axle-back system fits both standard 2-door (JK) and 4-door (JKU) Wrangler models equipped with 4-wheel drive and the 3.6L V6 engine. It installs as a straightforward, direct replacement for the original equipment rear muffler assembly, securing neatly to your factory mid-pipe connection while using your original hanger locations.
