It uses 2.5-inch tubing into the mufflers with dual 2-inch outlets and finishes with dual 4.25-inch by 2.5-inch oval polished T-304 stainless steel tips on each side. ATAK (Acoustically Tuned Applied Kinetics) delivers maximum volume and an assertive tone built for drivers who want the loudest street-legal Borla note. 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 premium T-304 austenitic stainless steel, with ultra-smooth mandrel bends for maximum flow and CNC-manufactured parts for an accurate 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, loudest)\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\u003eInlet diameter: 2.5 in\u003c\/li\u003e\n\u003cli\u003eOutlet diameter: 2 in (dual)\u003c\/li\u003e\n\u003cli\u003eTips: dual 4.25 in x 2.5 in oval, polished T-304 stainless steel\u003c\/li\u003e\n\u003cli\u003eExit style: dual split rear\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: 140428\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eVehicle Applications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e1997 Chevrolet Corvette\u003c\/li\u003e\n\u003cli\u003e1998 Chevrolet Corvette\u003c\/li\u003e\n\u003cli\u003e1999 Chevrolet Corvette\u003c\/li\u003e\n\u003cli\u003e2000 Chevrolet Corvette\u003c\/li\u003e\n\u003cli\u003e2001 Chevrolet Corvette\u003c\/li\u003e\n\u003cli\u003e2002 Chevrolet Corvette\u003c\/li\u003e\n\u003cli\u003e2003 Chevrolet Corvette\u003c\/li\u003e\n\u003cli\u003e2004 Chevrolet Corvette\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003ch5\u003eWhat vehicles does the Borla 140428 cat-back fit?\u003c\/h5\u003e\n\u003cp\u003eIt fits 1997-2004 Chevrolet Corvette C5 models with the 5.7L V8, including Base, Z06, 50th Anniversary Edition, and Indianapolis 500 Pace Car trims.\u003c\/p\u003e\n\u003ch5\u003eIs the Borla 140428 cat-back legal in all 50 states?\u003c\/h5\u003e\n\u003cp\u003eYes.
