Product Details

The Hooker 3901HKR Competition Long Tube Headers are engineered to deliver maximum exhaust flow and performance gains for your high-performance engine. These painted headers feature mandrel-bent tubing that maintains consistent diameter throughout each bend, ensuring smooth, unrestricted exhaust flow for increased horsepower and torque.

Key Features:

  • Lightweight yet durable 16-gauge steel tubing construction
  • Precision 5/16-inch machined flanges provide a leak-free seal
  • Tuned-length primary tubes optimized for enhanced performance across the RPM range
  • Long transition collectors reduce back pressure for improved flow
  • High-quality welds throughout for maximum durability and longevity
  • Designed for straightforward, trouble-free installation
  • Complete hardware kit included for bolt-on installation
  • Factory painted finish for corrosion resistance

Hooker headers are a proven choice for enthusiasts seeking reliable performance gains and quality construction. These competition-style long tube headers are designed to replace restrictive factory exhaust manifolds, freeing up power while maintaining excellent fitment.
