Injen 03-08 350Z Dual 60mm SS Cat-Back Exhaust w/ Built In Resonated X-Pipe

When you're ready to give your 2003-2009 Nissan 350Z a more aggressive sound and a noticeable boost in performance, this Injen SES TT cat-back exhaust system is a solid choice. What you get in the box is a complete kit: all the stainless steel tubing, mufflers with embossed Injen logos, a uniquely designed resonated X-pipe integrated into the system, and a pair of beautiful dual 4.5-inch titanium exhaust tips with a burnt finish. This system is designed to replace your factory exhaust from the catalytic converter back, making installation as straightforward as possible with no cutting or welding required.

Injen builds these systems from 60mm 304 stainless steel tubing that's mandrel-bent. Mandrel bending is key because it ensures the pipe keeps its full diameter throughout the bends, allowing for smooth, unrestricted airflow. This improved flow is what helps Injen claim up to 16 horsepower and 17 lb-ft of torque gains, which you'll feel when you get on the throttle. The system also features Injen's dual JDM-style round mufflers and a functional resonator with an integrated X-pipe, all TIG welded by hand in Pomona, California, for strength and durability. The investment cast stainless steel flanges and custom hangers are also included to make the installation process smoother.

This Injen SES TT exhaust is designed to bring out a distinctively Injen sound that's aggressive without being over the top, and the burnt titanium tips add a sharp visual flair to the rear of your 350Z. Everything you need for installation, including premium stainless steel hardware and hangers, is included in the kit.
