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

Boost power, improve throttle response, and give your Z or G35 the aggressive exhaust note it deserves with this precision-engineered stainless catback system—built for performance and durability.

Hear the VQ35DE the Way It Should Sound

The Nissan 350Z and Infiniti G35 Coupe are icons of the early 2000s import performance scene—known for their responsive handling, aggressive styling, and the legendary VQ35DE engine. But if you're still running the factory exhaust, you're leaving power on the table and missing out on one of the best-sounding V6s ever built.

This high-performance catback exhaust system replaces the restrictive stock setup with mandrel-bent T-304 stainless steel piping, allowing exhaust gases to exit faster and more efficiently. The result? Dyno-proven gains of 15–25 horsepower, improved low-end torque, sharper throttle response, and a deep, aggressive tone that brings out the VQ's signature growl without any annoying drone.
