aFe Twisted Steel 304 Stainless Steel Headers

Unleash more torque and horsepower from your Dodge or Chrysler 5.7L with this Twisted Steel series header. Made with 16-gauge 1-3/4" mandrel bent 304 stainless steel tubing and uses 4-to-1 mitered merge collectors to eliminate flow-block turbulence. The result is unrestricted exhaust flow for overall performance gains of up to +9 HP and +10 lbs. x ft. torque on our in-house dyno. 100% hand MIG welded for quality, strength and durability, this system also features ball flange connection, retains factory 02 sensor locations and includes metal gaskets and hardware for hassle-free install.

Performance Gains:

In-house dyno testing produced gains of up to +9 horsepower and +10 lbs. x ft. torque.

Optimized Tube Lengths:

Head tube lengths are optimized for true pulse control technology which improves flow and performance.

Mitered Collectors:

4-to-1 mitered merge collectors decrease turbulence and increase exhaust velocity. The result is increased horsepower, torque and improved throttle response.

Stainless Steel Construction:

Mandrel bent 1-3/4" 16-gauge 304 stainless steel tubing increases exhaust velocity for noticeable torque and horsepower gains.

Heavy Duty Flanges:

3/8" thick, 1-piece flanges prevent warpage to ensure a leak-free seal over the life of the vehicle.

MIG-Welded:

100% MIG-Welded by certified craftsmen to provide the strongest welds, reducing stress cracks for race proven strength and durability.

Factory Mounting Locations:

These headers retain your stock catalytic converters and factory 02 sensor locations for a direct bolt-on installation which requires no cutting or modifying.
