Exhaust Header Set LS Swap Polished 304 SS

The FLOWTECH Exhaust Header Set LS Swap Polished 304 Stainless Steel is a direct-fit shorty header solution engineered for LS engine swaps seeking improved exhaust scavenging and underhood clearance. Built from 304 stainless steel with a polished mirror finish, this pair delivers both functional performance and a clean aesthetic in the engine bay. The 1.625-inch primary tubes and 2.5-inch collector design optimize exhaust velocity across the RPM range while maintaining compatibility with tight LS swap installations where traditional long-tube headers create packaging conflicts.

The 304 stainless construction resists thermal cycling corrosion better than mild steel, critical in LS swap applications where headers experience sustained high temperatures. The polished finish provides corrosion protection while maintaining visibility during future service work. At 18.4 pounds total weight, this header set contributes minimal mass while the shorty profile minimizes heat soak issues that plague tighter engine compartments. Gaskets and mounting hardware are included, streamlining installation. The collector diameter of 2.5 inches represents the balance point between scavenging efficiency and clearance constraints typical in GM LS-series swap platforms.

This header set addresses a specific market: builders performing LS engine swaps into vehicles with limited underhood space—hot rods, imports, and mid-engine applications where traditional long-tube headers simply don't fit. The polished stainless finish appeals to builds where engine bay aesthetics matter. Street and weekend-track builders will appreciate the reduced installation complexity compared to custom-bent headers while retaining exhaust flow improvements over stock manifolds.

For LS swap buyers evaluating header options, shorty headers remain the practical choice when long-tube routing proves impossible. The FLOWTECH design prioritizes fitment and durability over maximum flow gains, making it suitable for street-driven conversions where reliability outweighs peak horsepower extraction.
