Catback Exhaust System for Infiniti G35 Base (2003-2007) 3.5L DOHC

Deepen the Signature VQ Growl with this Performance Catback for the Infiniti G35 & Nissan 350Z

Who It’s For: Designed specifically for enthusiasts piloting the 2003-2007 Infiniti G35 Coupe and the 2003-2009 Nissan 350Z equipped with the legendary VQ35DE and VQ35HR engine family.

The Problem: While the VQ35DE is world-renowned for its unique exhaust note, the factory system is heavily baffled and constructed from mild steel that eventually succumbs to corrosion. The stock 2.25-inch diameter in many sections is sufficient for a daily driver, but the restrictive muffler design creates backpressure that stifles the high-RPM potential of this V6.

The Solution: We engineered this stainless steel catback system to streamline exhaust gas velocity and amplify the natural acoustics of your engine. By utilizing mandrel-bent 2.25" piping and a high-flow dual slant roll muffler, this system reduces backpressure, allowing your VQ to breathe better and pull harder through the mid-to-high rev range.

Why This is the Ultimate Upgrade

• Optimized Flow: Mandrel-bent 2.25" piping provides a smooth path for exhaust gases, resulting in a dyno-proven gain of 10-20HP over the restrictive factory setup.
• Corrosion Resistance: 100% stainless steel construction with a mirror-polished finish ensures this system can handle heat cycles and road salt better than OEM mild steel.
• Aggressive Aesthetics: Massive 4.50" dual slant roll tips fill out the rear bumper cutouts perfectly, giving your G35 or 350Z a much more commanding presence on the street.

The Performance Promise

Professional installation is highly recommended. Like most performance exhaust systems, minor adjustments or welding may be required for perfect alignment depending on your header and Y-pipe configuration. This system is designed for off-road use and is intended to provide the deep, aggressive tone that the VQ engine is known for. Buy with confidence from automotive experts who know the Z/G platform inside and out.
