aFe Twisted Steel Headers, 2003-2006 350Z

Factory Mounting Locations:
These headers are a direct bolt-on installation which requires no cutting or drilling to provide a hassle-free installation.
Formed Collectors:
3-to-1 formed collectors decrease turbulence and increases exhaust velocity. The result is increased horsepower, torque and improved throttle response.
Heavy Duty Flanges:
1-5/8" thick one-piece flanges are used to prevent warpage to ensure a leak-free seal over the life of the vehicle.
Optimized Tube Lengths:
Tube lengths are optimized for true pulse control technology which improves flow and performance.

Included:
• Twisted Steel Headers
