ISR Performance MBSE Dual Exhaust - Infiniti G37 Sedan

The ISR Performance MBSE Dual Exhaust is a catback exhaust system for the 2009-2013 Infiniti G37 Sedan in both RWD and AWD configurations. Built from mandrel-bent stainless steel with dual 2.5-inch piping, larger rear mufflers and resonators, and polished muffler bodies. Delivers the unrestricted flow needed for boosted or built VQ37VHR builds while retaining a deep, aggressive tone the platform is known for.

What It Does

Catback replaces the entire exhaust system from the Y-pipe back, including the mid-pipe, resonators, and rear mufflers. The mandrel-bent 2.5-inch piping maintains a consistent inside diameter through every bend, which matters more on a build chasing power than on a stock car. Larger-than-factory rear mufflers and resonators keep the tone deep and controlled rather than raspy, which is the right balance for a sedan that often pulls double duty as a daily driver.

Fitment

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