ISR Performance GT Single Exit Exhaust – 2009–2020 Nissan 370Z | 3-Inch Stainless
Unlock the full character of your 370Z's VQ37VHR with the ISR Performance GT Single Exit Exhaust. A complete Y-pipe back system built from full 3-inch stainless steel, the ISR GT delivers proven power gains, an aggressive VQ exhaust note, and a race-inspired single exit aesthetic — all at exceptional value. Whether you're building a street car, a track day weapon, or a drift build, the ISR GT is a proven, no-compromise exhaust upgrade for the Z34 platform.
The single exit configuration reduces rear-end weight compared to the factory dual setup while giving your 370Z a distinctive, motorsport-inspired look that stands out from the crowd.
