Overview

A 2003-2008 Nissan 350Z 3.5L with a tired catalyst needs a replacement that keeps the readiness monitors happy. MagnaFlow's OEM Grade 51601 is built for exactly that job and bolts in without cutting or welding. Coverage spans 6 model years: 2003-2006 Nissan 350Z (Base, Enthusiast, Grand Touring, Performance, Touring and more), 2003-2007 Infiniti G35 (Base, Journey, Sport, X), 2003-2008 Infiniti FX35 (Base) and 2006-2008 Infiniti M35 (Base, Sport, X). It replaces the driver-side catalyst only; confirm the position on your vehicle before ordering. It ships at roughly 8 lb.
