ISR Performance Single GT Exhaust for Infiniti G37 Sedan RWD & AWD | 3” Stainless
ISR Performance Single GT Exhaust – Infiniti G37 Sedan RWD & AWD
The ISR Performance Single GT Exhaust is a high-flow, Y-pipe-back exhaust system built specifically for the Infiniti G37 Sedan (both RWD and AWD). Constructed from mandrel-bent stainless steel with precision TIG welds, this exhaust delivers improved performance and a deep, aggressive exhaust tone—perfect for both naturally aspirated and forced induction builds.
This lightweight system not only improves throttle response and horsepower potential, but also provides a bold exhaust note that remains refined during cruising and opens up under throttle.
