Product Details

The FlowTech Exhaust 11549FLT Shorty Headers are a popular choice for LT engine swaps, featuring high-quality stainless steel construction with a polished finish. These headers are engineered to deliver improved exhaust flow, increasing horsepower and torque while enhancing throttle response.

Key Features:

  • Mandrel-bent 409 stainless steel tubes with 1-5/8" diameter primary tubes for smooth, consistent flow and increased exhaust velocity
  • Heavy-duty 16-gauge tubing construction for enhanced strength and durability
  • TIG-welded, machined 3/8" thick header flange provides a leak-free seal and maximum strength
  • OE-style 2-1/2" ball and socket collector design connects directly to factory exhaust head pipe with no cutting or welding required
  • Premium aluminum header gaskets included for proper installation
  • Polished stainless steel finish for a clean, show-quality appearance

These shorty headers are designed specifically for LT-series engine swaps, offering a direct bolt-on solution that maximizes performance while maintaining compatibility with factory exhaust systems. The smooth transition design and optimized primary tube diameter work together to reduce exhaust backpressure and improve engine efficiency across the RPM range.
