Give your Gen 3 HEMI the exhaust flow and sound it deserves with Stainless Works Long Tube Headers, designed for compatible Dodge Challenger, Charger, Magnum, and Chrysler 300C applications equipped with 5.7L, 6.1L, 6.4L, or 6.2L Supercharged HEMI engines. These long tube headers are manufactured from corrosion-resistant 304 stainless steel and fully TIG welded for strength, durability, and a clean finished appearance, with your choice of 1-7/8-inch or 2-inch primary tubes to better match the airflow demands of your particular engine combination. Stainless Works includes high-flow catalytic converters and offers configurations designed to connect at the factory exhaust connection point or integrate with compatible Stainless Works exhaust systems. The long tube design improves exhaust scavenging to support increased horsepower and torque, with Stainless Works advertising gains of 15+ horsepower while leaving additional performance potential available when paired with other modifications and proper tuning. Whether you’re waking up a naturally aspirated 5.7L, building a cammed 392, or improving exhaust flow on a supercharged Hellcat, this system provides a proven foundation for a more complete Gen 3 HEMI performance combination.

Construction quality is a major part of the Stainless Works package, with the premium Stainless Works version manufactured in Streetsboro, Ohio, and backed by a lifetime warranty on materials and craftsmanship. The 304 stainless tubing is mandrel bent to maintain a smooth exhaust path through the bends, while TIG-welded construction provides the durability expected from an exhaust system designed for performance use.

Choosing the correct primary diameter allows the headers to better complement the rest of your build. The 1-7/8-inch option provides a strong choice for many naturally aspirated and moderately modified Gen 3 HEMI combinations, while the available 2-inch primaries provide additional exhaust capacity for combinations where increased airflow demands justify the larger tube diameter. Actual performance will depend on displacement, camshaft, cylinder heads, forced induction, exhaust configuration, tuning, and other modifications, because apparently engines insist on making us consider the whole combination instead of simply buying the biggest tube available.

Stainless Works also supplies the system as an install-ready package. The kit includes driver and passenger headers, two catalytic converters, two lead pipes, four adapters, stainless tubing, six O2 extensions, six clamps, a 16-piece bolt kit, RTV, and installation instructions. This helps eliminate the scavenger hunt for miscellaneous hardware and supporting pieces once the car is already apart.

Fitment covers 2008-2025 Challenger, 2006-2025 Charger, 2005-2008 Magnum, and 2005-2021 Chrysler 300C applications with supported HEMI engines. These headers do not fit AWD models, so drivetrain configuration should be confirmed before ordering. For properly matched rear-wheel-drive Gen 3 HEMI applications, Stainless Works long tube headers deliver improved flow, aggressive sound, quality stainless construction, and the hardware needed to make them a serious upgrade for street and performance builds.
