ISR Performance ST Series Exhaust - Nissan 370Z

The ISR Performance ST Series exhaust for the Nissan 370Z is a stainless steel Y-pipe back system that gives the Z34 a deeper, more aggressive tone and a cleaner look at the rear bumper. It bolts to the factory Y-pipe and replaces the stock mid-pipe and rear muffler, so the install is direct and does not involve cutting or welding.

System layout

From a 3 inch flange at the Y-pipe, the system splits into dual 2.5 inch pipes, each with a bottle-style resonator to tame drone. The pipes terminate in two muffler sections with polished 4 inch tips, filling the rear valance the way a Z34 should.
