Description

The American Racing Headers Long System is engineered to enhance both the sound and performance of your 2011-2026 Dodge Durango equipped with a 5.7L Hemi engine. This premium exhaust upgrade is constructed entirely from 304 stainless steel, ensuring durability and corrosion resistance, and features a 3-inch diameter throughout the system. The Pure Thunder Series mufflers are included to deliver an aggressive, race-inspired exhaust note. Key features of this system include its 100% USA-made craftsmanship, utilizing premium 304 stainless steel sourced domestically. The headers boast 3/8-inch thick laser-cut flanges for a precise, warp-free seal against the cylinder heads. Inlets are hand-ported and TIG welded for optimal flow, while the merge collectors are designed with scavenger spikes to maximize exhaust scavenging and performance gains. For catted versions, 200-cell metallic substrate catalytic converters are employed for exceptional durability and flow. American Racing Headers explicitly states that all their products are manufactured for racing purposes. Installing these headers on any vehicle eliminates their legal use on public roads and highways, and may be subject to fines or criminal liability under the Clean Air Act. This system is compatible with both 2WD and 4WD models of the Dodge Durango 5.7L Hemi from 2011 to 2026.
