GT Single Exhaust Y-Pipe Back System

The ISR Performance GT Single Exhaust system is engineered as a Y-pipe back, single-exit solution for the Infiniti G37 Sedan. The 3-inch inlet smoothly transitions to a prominent 4.5-inch tip, delivering an aggressive aesthetic and an enhanced exhaust note. Its Y-pipe back configuration ensures a straightforward installation process, replacing the stock components from the Y-pipe to the rear of the vehicle. The use of stainless steel not only contributes to its robust build but also offers resistance to corrosion, ensuring a lasting appearance and performance. Compatibility is specific to the Infiniti G37 Sedan models, including both RWD and AWD variants. For the Coupe models, a separate part number (IS-GT-G37C-ISR) is specified and confirmed to fit RWD versions from 2008-2013.
