ISR Performance GT Single Exhaust - Infiniti G35 Sedan 03-04

Our Single GT exhaust for the 03-04 G35 Sedan, the same family that's held a reputation across the Z platform for clean fitment, deep tone, and unrestricted flow. Y-pipe back, mandrel-bent stainless, single 4.5" polished tip.

What It Does

Replaces the factory cat-back with a free-flowing single-exit system in 3" mandrel-bent stainless. Opens up airflow on the VQ35DE without going overboard on volume. The single exit keeps things subtle while still delivering the deep, aggressive tone the Single GT family is known for. Works equally well on naturally aspirated and forced induction setups.

Fitment

Fits the 2003-2004 Infiniti G35 Sedan, RWD only. The AWD G35x uses different exhaust routing and is not compatible. For 2005-2006 G35 Sedan applications, use IS-GT-G35SDN instead. For a full system, pair this with the IS-Z33-Y aftermarket Y-pipe, which the G35 RWD shares with the 350Z.
