ISR Performance Single GT Exhaust - Infiniti G37 Sedan

The ISR Performance Single GT Exhaust is a Y-pipe-back single-exit exhaust system for the Infiniti G37 Sedan in both RWD and AWD configurations. Built from mandrel-bent stainless steel with a 3-inch pipe and 4.5-inch polished muffler tip, it opens up flow over the factory exhaust while delivering the deep, aggressive tone the VQ37VHR is known for.

What It Does

Y-pipe-back replacement that bolts up to the factory Y-pipe and runs back to a polished muffler with a 4.5-inch exit tip. The 3-inch mandrel-bent piping maintains a consistent inside diameter for unrestricted flow, and the stainless construction keeps weight down compared to the factory exhaust. Single-exit packaging works well on the sedan where the rear bumper layout doesn't accommodate dual exits as cleanly as the coupe.

Fitment

G37 Sedan only. Works on both RWD and AWD configurations. Not compatible with G37 Coupe or G37 Convertible.
