Show original supplier description
The Speed Engineering 25-1026 long tube headers are crafted from premium 304 stainless steel, ensuring durability and corrosion resistance. These headers feature 1-7/8" primary tube diameter and a 3" collector, optimized for enhanced exhaust flow. They are designed to fit LS engine swaps, specifically compatible with 4.8L, 5.3L, 6.0L, and 6.2L engine displacements. These headers are engineered for various applications including C10 trucks, A-body, F-body, and X-body vehicles. They are noted for providing perfect ground clearance, which is beneficial for vehicles with air ride suspension. The headers are mandrel bent and tig welded for precise fitment and optimal performance. Installation notes suggest that for some applications, a modified or aftermarket crossmember may be required. Speed Engineering headers have been dyno-proven for performance gains. The natural, raw stainless steel finish provides a classic look. These long tube headers are a direct fit for many LS swap applications, offering a balance of quality, performance, and affordability for enthusiasts looking to upgrade their exhaust system.
