Catback Exhaust System with Burnt Muffler Tip Style for Nissan 350Z (2003-2009) / Infinity G35 2-Door Coupe (2003-2007) 3.5L Engines

Stainless Catback Exhaust System for Nissan 350Z & Infiniti G35 Coupe

Upgrade your exhaust flow and transform the sound of your vehicle with this high-performance stainless catback exhaust system, engineered for the Nissan 350Z and Infiniti G35 Coupe equipped with the 3.5L engine. Designed to replace the restrictive factory exhaust, this system improves efficiency, increases power, and delivers an aggressive yet smooth exhaust tone.

Crafted from high-quality T-304 stainless steel, the exhaust features computerized mandrel-bent piping to maintain consistent diameter and optimal exhaust flow throughout the system. Precision TIG welding combined with CNC-machined flanges ensures excellent strength, resistance to pressure, and long-term corrosion protection.

The double-walled rolled tips add a clean, performance-focused finish while contributing to a deep, refined exhaust note. Under acceleration, the exhaust produces an aggressive, smooth tone without unnecessary restriction, helping exhaust gases exit more efficiently. Dyno testing shows gains of approximately 15–25 horsepower and improved low-end torque, resulting in better throttle response and overall engine performance.
