      Description

      Performance Exhaust Solution. The Flowtech 1-5/8-Inch LS Swap Shorty Headers in 304 Stainless Steel with a Polished Finish provide an efficient pathway for exhaust gases in GM LS engines, enhancing performance by reducing backpressure and improving exhaust flow. Designed for engine swaps and upgrades, these shorty headers offer an excellent balance of fitment and power gains for enthusiasts seeking a high-quality upgrade.

      Construction and Appearance. Crafted from premium 304 stainless steel, these headers feature mandrel-bent 1-5/8-inch primary tubes and 2-1/2-inch collectors optimized for flow. The polished finish offers a high-gloss, durable surface that resists corrosion and heat, while the 3/8-inch thick flanges ensure a secure, leak-free seal to the cylinder heads.

      Installation. Installation is straightforward with the included hardware and premium gaskets, requiring no special drilling for most applications. Due to the universal design, some adaptation might be necessary, but all mounting components are provided to assist with fitment.

      Application. Fits universal GM LS engines, including LS1, LS2, LS3, LS6, and LSX configurations; some adaptation may be needed because of the universal fitment nature.
