Description

High-Performance Turbo Headers. The Flowtech 1-3/4-Inch LS Turbo Headers in 304 stainless steel with a polished finish are engineered to optimize exhaust flow and engine efficiency for GM LS engines. They improve cylinder scavenging and reduce exhaust restrictions, resulting in increased performance and better throttle response for turbocharged V8 applications.

Construction and Appearance. Made of heavy-duty 16-gauge 304 stainless steel with a polished finish, these headers feature CNC mandrel-bent tubing that maintains consistent diameters for smooth exhaust flow. The design includes a robust 7/16-inch thick header flange and a 3-inch collector with V-band flanges and clamps to ensure a secure, leak-free fit. Premium aluminum header gaskets are included for proper sealing.

Installation. Designed for bolt-on installation requiring moderate mechanical skills, these headers do not include bolts or mounting hardware, so additional parts may be necessary. No drilling is typically required.

Application. Compatible with a wide range of GM Gen III and IV LS engines, these headers offer a universal fit that may require some adaptation for specific turbo setups. This product is intended for racing use only and is not compliant with emissions regulations.
