Catback Exhaust System for Nissan 350Z G35 3.5L Coupe Only (2003-2009) 3.5L DOHC

Maximize Throttle Response and Sound on Your VQ35-Powered Nissan 350Z & Infiniti G35

Who It’s For: Designed specifically for Nissan 350Z and Infiniti G35 owners running the VQ35 engine family who want a more aggressive acoustic profile and improved exhaust scavenging.

The Problem: The factory exhaust system on the VQ35 is notoriously heavy and restricted by narrow piping and bulky resonators. This setup often mutes the signature V6 tone and creates backpressure that limits the high-revving potential of the dual overhead cam design.

The Solution: We engineered this catback system to streamline exhaust flow with 2.25" mandrel-bent stainless steel piping. By reducing restriction, we corrected the factory flow limitations of the VQ35, allowing the engine to breathe more efficiently while delivering the deep, resonant tone enthusiasts demand.

Why This is the Ultimate Upgrade

• Performance Gains: Experience a dyno-tested increase of 10-20HP and improved throttle response across the RPM band.
• Marine-Grade Durability: Constructed from 100% stainless steel with a mirror-polished finish to resist corrosion and heat cycling fatigue.
• Aggressive Aesthetics: Features massive 4.50" dual slant-cut rolled tips that perfectly fill the factory bumper cutouts for a premium, custom look.
