The Borla(R) ATAK(R) system 140826CFBA, is specifically tuned for performance and sound on the GR Supra?s 3.0L twin-scroll turbocharged inline six engine. Our system is designed to be drone-free so you can get the head-turning sound of the ATAK(R) and still enjoy a comfortable cabin during cruise. This Cat-Back(TM) features a 3.5" pipe diameter that splits into dual 3" and comes with 4.5" Carbon Fiber tips with black anodized centers to complete the look of the exhaust. It includes our Polyphonic Harmonizer technology 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 appropriate for this ATAK(R) system. The system also has a functioning valve that works with the factory actuator to change the exhaust volume. As with all Borla(R) products, it is constructed using T-304 stainless steel for increased durability and is backed by our Million Mile Warranty. Bolt-on a Borla(R) and give your Supra the sound it deserves.
