Borla ATAK Cat-Back Exhaust System with 4-Inch Polished Tips (140382) - 2005-2009 Ford Mustang GT 4.6L & 2007-2009 Shelby GT500 5.4L V8
Wake up the high-performance spirit of your muscle car with the high-impact Borla ATAK Cat-Back Exhaust System. Custom-engineered for 2005 to 2009 Ford Mustang GT and 2007 to 2009 Mustang Shelby GT500 models, this premium full-length exhaust upgrade introduces Borla's legendary acoustic profile: the ultra-aggressive ATAK sound level. Formulated explicitly for driving enthusiasts and track purists who crave a highly aggressive, race-inspired exhaust note under acceleration, this system is calibrated to give the 4.6L 3-Valve V8 and the supercharged 5.4L V8 engines a bold, crisp, and high-impact growl. This configuration delivers an incredibly potent, track-grade acoustic presence on Shelby GT500 builds 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 commuting, or spirited driving.
The internal engineering of the Borla 140382 targets key factory flow restrictions by incorporating an upgraded high-efficiency performance layout featuring a 2.5-inch diameter mandrel-bent main pipe configuration. This performance architecture utilizes ultra-smooth mandrel bends and a straight-through multi-core configuration that maximizes exhaust velocity to unlock hidden horsepower, sharper throttle response, and enhanced fuel economy across the entire powerband. Designed to route flawlessly along the undercarriage, it leaves plenty of extra flow capacity for additional aftermarket performance modifications down the road, making it the perfect match for forced induction setups. 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 severe corrosion. The spent exhaust gases exit through a distinctive single split rear configuration featuring dual 4-inch round, rolled edge angle-cut bright chrome polished T-304 stainless steel tips on each muffler assembly. Precision CNC-manufactured for an accurate line-to-line bolt-on fitment, this system utilizes all factory mounting positions and is backed by Borla's legendary lifetime Million-Mile Warranty.
Chassis & Configuration Notes: This cat-back system is engineered specifically for the rear-wheel drive (RWD) S197 platform Ford Mustang equipped with either the naturally aspirated 4.6L V8 or the supercharged 5.4L V8 engine. It fits both automatic and manual transmission configurations across Coupe and Convertible body styles. Please note that this system is formulated strictly for the 2005 to 2009 design parameters where floor pan routing and original equipment hanger locations match this calibrated assembly.
