Borla ATAK Cat-Back Exhaust System with 4-Inch Polished Tips (140458) - 1999-2004 Ford Mustang GT & Mach 1 4.6L V8
Wake up the high-performance spirit of your muscle car with the high-impact Borla ATAK Cat-Back Exhaust System. Custom-engineered for 1999 to 2004 Ford Mustang GT and Mach 1 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 SOHC 2-Valve and 4V DOHC V8 engines a bold, crisp, and high-impact growl. This configuration delivers an incredibly potent, high-volume 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, daily commuting, or spirited track days.
The internal engineering of the Borla 140458 targets key factory flow restrictions by incorporating an upgraded high-efficiency performance layout featuring a 2.5-inch diameter main pipe configuration throughout. This performance architecture utilizes ultra-smooth mandrel-bent performance tubing and customized internal muffler geometry that maximizes exhaust flow CFM and cancels high-frequency sound waves. This advanced design helps 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 perfectly suited for high-horsepower builds, custom headers, or forced induction setups. Built completely from premium-grade, aerospace-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 premium 4-inch round, rolled edge angle-cut bright chrome polished T-304 stainless steel tips on each tailpipe. 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 2.5-inch cat-back system is engineered specifically for the rear-wheel drive (RWD) New Edge Mustang platform equipped with a factory solid rear axle (SRA). It fits 1999 to 2004 Mustang GT and 2003-2004 Mach 1 2-door Coupe and Convertible models equipped with both manual and automatic transmissions. Please note that this system is tailored specifically to route correctly around a solid rear axle and is not compatible with SVT Cobra models featuring Independent Rear Suspension (IRS).
