Borla 140743BC 2018 Ford Mustang GT 5.0L AT/MT 3in ATAK Catback Exhaust Black Chrome Tips w/ Valves
System will fit Bullitt models. NOT recommended for use on Convertibles. This 3" diameter high flow Cat-Back system was designed specifically for the Mustang GT has Active Exhaust Valves. Includes 2) 3" O.D. x 2.25" O.D. x 7" long adapters for clamp on installation to the stock exhaust system. Do not use the adapters for full 3” inlets. The system features a Merge X-Pipe for increased performance and improved sound. The system has BORLA®'S Polyphonic Exhaust Harmonizer which utilizes patented units that contain pipes of different diameters and lengths to create multiple exhaust notes that harmonize to deliver a clean, rich, full-bodied sound to the BORLA® mufflers. The mufflers then enhance this sound to the character and volume of the aggressive ATAK® sound, with no drone inside the vehicle. The exhaust exits thru dual 4" round black chrome on T-304 stainless steel tips on each muffler. Using BORLA® Stainless Steel Polish p# 21499 is NOT recommended with these black chrome tips. We suggest cleaning the tips with hot water and a microfiber cloth. Systems with bright chrome on T-304 stainless steel tips, and carbon fiber tips are also available.
BORLA® Cat-Back™ and Axle-Back and Axle-Back exhaust systems feature patented straight-through and multi-core technology designed to unleash hidden horsepower. Increased exhaust velocity adds power, driving excitement, fuel economy, and the distinctive BORLA® Sound of Power respected by motoring enthusiasts everywhere.
Each system is built from premium T-304 stainless steel, superior to T-400 series knockoffs (such as 409), to give you the absolute best in performance and durability. Ultra-smooth mandrel bends ensure maximum flow & power, and precision computer numerical control (CNC) manufacturing ensures an accurate fit.
Best of all, BORLA® stands behind every system with a Million-Mile Warranty. Just what you'd expect from the world's most experienced (and most winning) exhaust brand.
