LS 304ss Turbo Headers Up & Forward Style

The FLOWTECH LS 304 Stainless Steel Turbo Headers in Up & Forward style deliver precision-engineered exhaust flow for LS-series engine builds. These polished stainless steel headers feature 1.75-inch primary tubes and a 3-inch collector, purpose-built for turbo applications where header positioning and flow efficiency directly impact boost response and overall system performance. The up and forward configuration positions the collector to clear tight engine bays common in retrofit and custom builds, while the 304 stainless construction resists thermal cycling and corrosion inherent to forced-induction environments.

The 1.75-inch primary diameter represents the optimal balance for turbo LS applications—large enough to minimize backpressure and scavenging losses across the RPM band, yet sized to maintain velocity needed for efficient turbocharger spool-up. The 3-inch collector concentrates exhaust flow into the turbine inlet without creating dead zones that rob horsepower. Gaskets are included, eliminating the need for separate purchases and ensuring a complete, correct installation. Polished 304 stainless finish provides both durability against heat cycling and a professional appearance visible in engine bays with headers on display.

These headers address the needs of LS turbo builders working with universal mounting scenarios—whether in truck engine swaps, hot rods, or performance platforms where standard header fitment won't clear the chosen turbo layout. The up and forward angle is particularly valued in tight quarters where traditional side-exit or downward-exit designs create packaging conflicts. GM LS-series compatibility ensures fitment across the broadest engine family, from LS1 through modern variants, making these headers a dependable choice for turbo system integration in custom applications.
