ST Series Y-Pipe Back Exhaust System

The ISR Performance ST Series Exhaust is a Y-Pipe Back exhaust system engineered for the 2003-2007 Nissan 350Z. It begins with a 3-inch inlet flange and splits into dual 2.5-inch pipes, each featuring bottle-style resonators to refine the exhaust note. The system culminates in aggressive mufflers with 4-inch tips, designed to provide a deep, desirable tone for enthusiasts. This exhaust is a direct bolt-on replacement for the factory mid-pipe and rear muffler, simplifying installation. The kit includes all necessary gaskets and hardware for a straightforward setup. The primary benefit of this exhaust system is a louder and more aggressive exhaust note, enhancing the driving experience of your 350Z. It is specifically designed to fit 2003-2007 Nissan 350Z RWD models.
