High-Performance Turbo Headers. The Flowtech 1-7/8-Inch LS Turbo Headers in 409 Stainless Steel with a natural semi-gloss finish deliver advanced exhaust flow control designed specifically for GM LS V8 engines. Intended exclusively for racing use, these headers optimize turbo installation while improving cylinder scavenging and engine breathing to enhance throttle response and power output.
_x000D__x000D_Durability And Design. Constructed from heavy-duty 16-gauge 409 stainless steel tubing, these headers feature CNC mandrel-bent tubes for consistent diameter and smooth exhaust flow. The natural semi-gloss finish complements the robust construction with a 3-inch V-band collector and a thick 7/16-inch flange engineered to provide a durable, leak-free seal.
_x000D__x000D_Installation. Installation requires moderate mechanical skill and no drilling, thanks to the included premium aluminum gaskets and V-band clamps. Bolts and mounting hardware are not included, so prior preparation is recommended to ensure proper fitment.
_x000D__x000D_Application. These headers fit GM LS engines ranging from 4.8L to 7.0L and are intended for use on racing or off-road vehicles only. Installation on emissions-controlled vehicles is prohibited by law and strictly restricted to competition use.
