Upgrade the sound, performance, and style of your coupe with the ISR Performance Single GT Exhaust for Infiniti G37 Coupe RWD. Designed for enthusiasts who demand maximum flow and an aggressive exhaust note, this Y-pipe-back exhaust system delivers the perfect balance of power, tone, and lightweight construction.
Constructed from mandrel-bent stainless steel, the ISR Single GT Exhaust ensures smooth exhaust flow for improved horsepower and throttle response. The unrestricted 3-inch piping is engineered to support both naturally aspirated and forced induction setups, making it an ideal performance upgrade whether you’re stock or modified. Precision TIG-welded construction and a brushed stainless finish provide long-lasting durability with a clean, performance-driven appearance.
This system produces a deep, aggressive exhaust tone without unnecessary restriction, giving your G37 Coupe a powerful sound that matches its performance potential. A slightly raised mid-section is incorporated to improve W-brace clearance, ensuring proper fitment while maintaining optimal ground clearance. The system is also lighter than the factory exhaust, helping reduce overall vehicle weight for improved performance.
Finished with a polished muffler and 4.5-inch polished exhaust tip, the Single GT Exhaust adds a bold, sporty look to the rear of your Infiniti. For added versatility, this exhaust includes a flange adapter, allowing it to bolt directly to the factory Y-pipe for straightforward installation.
