The ARK N-II Exhaust are built for absolute performance and sound. The WRX/STI System is designed with larger diameter pipping to improve flow and increase performance. Each N-II System is constructed of high quality T304 Stainless Steel for durability and longevity. This is a great system for the enthusiast that is focused on power and performance, but still wants a good sounding exhaust.
ARK Performance were one of the first companies to use helmholtz resonant chambers on their exhausts and has become a signature feature on the N-II systems. These reservoir tanks (helmholtz resonant chamber) are specifically designed to reduce in-cabin drone by canceling and eliminating specific sound frequencies. By adding these tanks, it may also increase airflow which results in more power.
