Build your LS-swapped Mustang with these high-performance stainless steel long tube headers, designed specifically for GM LS engine conversions in 1979–1993 Fox Body and 1994–2004 SN95/New Edge Mustang chassis.
Featuring 1-7/8-inch mandrel-bent primary tubes, a 3-inch collector outlet, and CNC-machined header flanges, these headers are designed to support exhaust flow and scavenging in naturally aspirated and boosted LS builds. The polished 304 stainless steel construction provides a clean finish, while included graphite gaskets support installation.
Designed for use with compatible LS swap components, these headers are best suited to builds using a tubular aftermarket K-member, LS swap mounts, and an aftermarket steering shaft. Actual clearance depends on engine placement and the components used in your conversion.

K-member compatibility: A tubular aftermarket K-member is commonly used in these conversions to help accommodate engine placement and header clearance. The factory K-member may present clearance limitations.
Steering shaft clearance: Steering shaft position can affect header fitment. An aftermarket steering shaft may be needed, depending on the swap configuration.
Engine mount position: LS swap mounts influence engine placement and clearance around the firewall, K-member, steering components, and headers.
Exhaust integration: The 3-inch collector outlets can serve as connection points for compatible custom exhaust systems. Additional exhaust routing or fabrication may be required for the specific build.
