GM LS1-LSX Turbo Headers

The Stainless Works GM LS1-LSX Turbo Headers are purpose-built exhaust manifolds designed for LS-series engine swaps incorporating turbocharger systems. These headers feature 1.875-inch primary tubes that transition into a 3-inch collector, optimizing exhaust scavenging for forced-induction applications. Constructed from stainless steel and offered in natural finish, this pair delivers the corrosion resistance and thermal durability demanded by high-performance turbo builds while maintaining structural integrity under sustained boost pressure.

The 1.875-inch primary diameter is engineered to match the optimal flow characteristics for turbocharged LS engines, balancing back-pressure and scavenging efficiency across a broad RPM range. The upswept design clears engine bay components common to LS-swap installations while directing exhaust gases directly into the turbocharger inlet with minimal restriction. Stainless steel construction resists oxidation and thermal cycling fatigue, critical factors when turbocharged exhaust temperatures routinely exceed 1,200°F. Hardware is included, streamlining installation into fabricated or modified mounting points. These headers are sold as a complete pair for both cylinder banks.

LS turbo swaps demand exhaust components engineered specifically for forced-induction duty. Whether upgrading a street machine, track vehicle, or custom project build, proper header selection directly impacts turbo spool response, peak boost levels, and long-term reliability. Buyers fabricating turbo manifolds or sourcing OEM-equivalent components will find these Stainless Works headers a vetted solution that eliminates custom mandrel-bending and welding work. The natural stainless finish requires no additional coating and develops a distinctive patina under heat.

LS-series powerplants have become the platform of choice for engine swaps across multiple vehicle platforms. Turbocharger kits and manifold systems continue evolving, but properly matched headers remain fundamental to maximizing efficiency and supporting consistent power delivery. The 3-inch collector diameter accommodates common turbo inlet flanges and downpipe configurations found in both street and competition builds.
