ISR Performance Single GT Exhaust for Infiniti G37 Sedan

Upgrade the sound, performance, and attitude of your Infiniti G37 Sedan with the ISR Performance Single GT Exhaust System, engineered for drivers who want maximum flow, aggressive tone, and race-inspired styling without compromising reliability.

Designed as a Y-pipe back exhaust system, the ISR Single GT exhaust is constructed from mandrel-bent stainless steel, ensuring smooth exhaust flow and long-lasting durability. By reducing restriction compared to the factory exhaust, this system helps unlock maximum horsepower potential while significantly cutting weight for improved overall performance.

The 3-inch single-exit design promotes unrestricted exhaust flow, making it an excellent choice for both naturally aspirated and forced induction setups, including turbocharged or supercharged builds. Precision TIG-welded stainless steel construction ensures strength under high heat and performance conditions, while the brushed stainless finish delivers a clean, motorsport-inspired look.

Sound is where the Single GT truly shines. This exhaust delivers a deep, aggressive exhaust note that turns heads without sounding thin or raspy.
