The focus of ATAK is to retain clarity of sound, avoiding the terrible drone and distortion typically found in louder exhaust kits. The development of this ATAK system required the extensive research of the acoustical properties of the exhaust on a 3.7L V6 Mustang. The internal muffler cores contain the heart of the ATAK technology, and each vehicle's exhaust is calibrated to deliver the most desirable sound. With the release of BORLA's ATAK system for for the 3.7L V6 Mustang (2011, 2012, 2013, and 2014 are included), MPT Performance is excited to offer you this exhaust featuring master craftsmanship, premium 300-series austenitic stainless steel construction, mandrel bends, and the use of computer controlled CNC machinery to deliver exact fitment, perfect bends and maximum airflow every time. Polished tips and BORLA's Million Mile Warranty round out this package for a complete performance cat-back exhaust replacement.
