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.
Hassle-Free Installation: Factory style metal header gaskets and all necessary hardware are included for a hassle-free installation.
