System, Chrome Tips | 140458","description":"\u003cp\u003eThe Borla ATAK cat-back exhaust system brings an aggressive sound and outstanding flow to the 1999-2004 Ford Mustang GT, Bullitt, and Mach 1 with the 4.6L V8. This 2.5-inch cat-back system uses a unique muffler and exhaust configuration that cancels high-frequency sound waves while delivering a significant increase in exhaust flow over the factory system, and finishes with a single 4-inch round bright chrome tip on T-304 stainless steel on each tailpipe. Borla cat-back systems use patented straight-through, multi-core technology to free hidden horsepower, increasing exhaust velocity for added power, efficiency, and the distinctive Borla Sound of Power. Each system is built from aerospace-grade T-304 austenitic stainless steel, superior to 409 or aluminized steel, with ultra-smooth mandrel bends for maximum flow and CNC-manufactured parts for an accurate bolt-on fit, and is backed by the Borla Million-Mile Warranty. This system mounts behind the factory catalytic converters and is 50-state emissions legal. Borla exhaust is handmade in the USA.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSystem type: Cat-back exhaust system\u003c\/li\u003e\n\u003cli\u003eSound level: ATAK (aggressive)\u003c\/li\u003e\n\u003cli\u003eMaterial: T-304 austenitic stainless steel\u003c\/li\u003e\n\u003cli\u003eConstruction: fully welded, mandrel-bent, straight-through multi-core mufflers\u003c\/li\u003e\n\u003cli\u003eTubing diameter: 2.5 in\u003c\/li\u003e\n\u003cli\u003eTips: single 4 in round, bright chrome on T-304 stainless, one per tailpipe\u003c\/li\u003e\n\u003cli\u003eEmissions: 50-state emissions legal\u003c\/li\u003e\n\u003cli\u003eWarranty: Million-Mile Warranty\u003c\/li\u003e\n\u003cli\u003eMade in the USA\u003c\/li\u003e\n\u003cli\u003ePart number: 140458\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eVehicle Applications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e1999 Ford Mustang GT\u003c\/li\u003e\n\u003cli\u003e2000 Ford Mustang GT\u003c\/li\u003e\n\u003cli\u003e2001 Ford Mustang GT\u003c\/li\u003e\n\u003cli\u003e2001 Ford Mustang Bullitt\u003c\/li\u003e\n\u003cli\u003e2002 Ford Mustang GT\u003c\/li\u003e\n\u003cli\u003e2003 Ford Mustang GT\u003c\/li\u003e\n\u003cli\u003e2003 Ford Mustang Mach 1\u003c\/li\u003e\n\u003cli\u003e2004 Ford Mustang GT\u003c\/li\u003e\n\u003cli\u003e2004 Ford Mustang Mach 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003ch5\u003eWhat vehicles does the Borla 140458 cat-back fit?\u003c\/h5\u003e\n\u003cp\u003eIt fits 1999-2004 Ford Mustang GT, the 2001 Bullitt, and the 2003-2004 Mach 1, all with the 4.6L V8.\u003c\/p\u003e\n\u003ch5\u003eIs the Borla 140458 cat-back legal in all 50 states?\u003c\/h5\u003e\n\u003cp\u003eYes.
