Fitment Information
- Infiniti G35 Coupe V35 VQ35DE RWD (2003, 2004, 2005, 2006, 2007)
- Coupe only, does not fit Sedan or AWD G35X
Fitment Note: G35 Coupe RWD only. Does not fit the G35 Sedan, which uses a different exhaust routing and has a separate ISR GT exhaust available. Does not fit AWD G35X models. This is a purpose-built G35 Coupe exhaust, not an adaptation of a 350Z exhaust using an extension pipe. ISR designed this system specifically for the G35 Coupe chassis to ensure perfect fitment and optimal ground clearance, which is a known issue with 350Z-based exhausts fitted to the G35 using extension adapters.
