aFe® (05-21) Mopar 5.7L Twisted Steel™ 304SS Catless Mid-Pipes

If you are looking for improved performance, throttle response, and enhanced sound to your aftermarket exhaust, aFe POWER has a header for your gas powered car or truck. Twisted Steel headers are TIG or MIG-welded by certified craftsmen for race proven strength and durability. TIG-welding provides the strongest welds reducing stress cracks. Our headers are designed to increase exhaust velocity and increase usable torque. This results in a more aggressive throttle response and increased passing power. Tuning may be required depending on application. 

CNC Laser-Cut Flanges 

Ensures a leak free seal and hassle-free installation.

100% Welded by Hand 

TIG/MIG-welding provides a strong weld which reduces stress cracks and failure.

Mitered/Formed Merge Collectors 

Mitered merge collectors increase exhaust velocity, reduce exhaust turbulence and maximize performance.

Header Technology 

American Muscle Performance Headers

Twisted Steel Headers are constructed out of 304 Stainless Steel for maximum durability. Our headers are designed with formed collectors which decreases turbulence and increases air velocity for improved air flow. Primary tubing can vary from 1-3/4" to 1-7/8" depending on vehicle application, while the flanges are laser cut 3/8" thick for precision cutting and port matched for the ultimate leak free seal. 

Every header is developed and designed to the highest standards and include all the hardware you need to do a hassle free install. Each header is specifically designed to increase horsepower, torque, and throttle response to enhance your vehicle's experience and overall drivability without having to alter a thing on the vehicle.
