Show original supplier description
The Speed Engineering LS Swap Longtube Headers are engineered for LS engine conversions in 1979-1993 and 1994-2004 Ford Mustang Fox Body vehicles. They feature 1 7/8" primaries that merge into a 3" collector, designed to maximize exhaust scavenging and performance. Key features of these longtube headers include CNC machined flanges for a precise seal and the inclusion of Standard Graphite Manifold Gaskets. They are designed to provide significant exhaust flow improvements, with claims of over 25+ rwhp gains. These headers are specifically intended for V8 LS engines, including 4.8L, 5.3L, 6.0L, 6.2L, LS1, LS2, LS3, LS6, and LSA variants. It is important to note that these headers are for GM LS engine swaps only and are not compatible with Ford engines. The product is designated as RACE ONLY, intended solely for competition purposes and not for use on public roads or highways. Installation will require fabrication. Additionally, the product listing indicates the headers are currently out of stock with an estimated availability of 7/31. This product is bundled with an AJE K-Member, LS Engine Motor Mounts, and Spring Perches compatible with 1979-2004 Mustang A-Arms and Springs.
