High Flow Cat

The ISR Performance High Flow Cat is engineered for the Nissan 240sx models from 1989 to 1998 (S13 and S14 chassis). It utilizes a 300-cell spun metallic substrate to provide a less restrictive exhaust flow compared to the factory catalytic converter, potentially leading to increased power output. In addition to improved exhaust flow, the ISR Performance HFC contributes to a more aggressive exhaust note. It is crucial to note that this product is designated **for off-road use only**. Its use is legally restricted to competition vehicles that will not be registered, licensed, or operated on public streets or highways, as well as other exempted vehicle types. Installation on vehicles intended for street use may be in violation of local emissions regulations.
