The Ultimate LS Swap Solution for GM S10

Performing an LS swap in your 1982-2004 GM S10 truck has never been easier. FlowTech Shorty Headers are precision-engineered to provide the clearance required for the LS-series engine swap, ensuring a seamless installation. These headers are crafted from high-quality stainless steel, offering superior corrosion resistance and durability compared to standard mild steel alternatives.

Why Choose FlowTech LS Swap Headers?

  • Designed specifically for GM LS-series engine swaps in S10 chassis
  • 1.625-inch primary tubes maximize exhaust velocity
  • 2.25-inch collector diameter for balanced backpressure
  • Natural stainless steel finish for long-lasting aesthetics
  • Complete kit includes gaskets and hardware for a bolt-on experience

These shorty headers are designed to fit the tight confines of the S10 engine bay, providing excellent clearance for steering shafts and frame rails. By optimizing the exhaust path, you will notice improved throttle response and a deeper, more aggressive exhaust note. Whether you are building a daily driver or a track-focused truck, these headers are designed to handle the increased power output of an LS engine. Don't settle for restrictive factory manifolds when you can upgrade to a performance-proven exhaust system. Get the best fitment and flow for your project at GGCRACING.
