Description
Performance Exhaust Headers. The Flowtech 1-5/8-Inch LS Swap Shorty Headers in 304 Stainless Steel with a Natural Finish are engineered to optimize exhaust flow for GM LS engines, enhancing both performance and efficiency. Designed specifically for engine swaps and upgrades, these headers improve exhaust evacuation and support increased power output in racing and off-street applications.
Construction and Appearance. Crafted from durable 304 stainless steel, these headers feature mandrel-bent primary tubes and thick 3/8-inch flange construction for rigidity and a leak-free seal. The natural finish provides a semi-gloss silver appearance that resists corrosion and maintains a clean under-hood look.
Installation. Installation of these headers is moderately straightforward for experienced installers and typically requires no drilling due to the included hardware and gaskets. Minor modifications or adaptation may be necessary depending on specific vehicle configurations during engine swaps.
Application. Designed to fit universal GM LS platforms including popular LS1, LS2, LS3, LS6, and LSX engines; some adaptation may be required depending on specific vehicle setups and mounting configurations.
