Features:
•Constructed of 1-5/8" 16-gauge 304 stainless steel primary tubing
•Mandrel-bent for unrestricted flow
•3-to-1 formed collectors decrease turbulence and increases exhaust velocity
•Optimized Tube Lengths Improve Flow and Performance
•100% hand TIG-welded construction ensures optimal strength and durability

Test Results:
•In testing, the headers produced a max gain of +9 horsepower and +11 ft. lbs. of torque verified by our in house dyno* (tested on 2003 Nissan 350Z V6-3.5L)
•Potential for up to +16 horsepower and +15 lbs. x ft. of torque when combined with aFe's performance Y-Pipe (P/N 48-36104-YC)

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 1-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.

aFe headers and exhaust are engineered and manufactured in our Corona, California manufacturing facility.
