About this item

  • Optimal Flow and Fit: CNC mandrel bent tubes provide accurate fit and better flow for improved performance
  • Enhanced Horsepower: Precision formed long transition collectors and long tube design reduce backpressure and increase higher RPM horsepower
  • Durability and Longevity: Heavy 16-gauge 304 stainless tubing ensures longer life and durability
  • Leak-Proof Sealing: 3/8" thick flanges with machined sealing beads ensure no leak performance
  • Polished Finish: Exhaust tubes are polished to remove any scratches, leaving a reflective, clean and polished appearance


Doug's places a premium on performance, quality, and fit. Each header is precision-tuned for maximum exhaust efficiency, resulting in substantial gains in horsepower and torque. Our headers undergo meticulous development and rigorous testing on dedicated vehicle models to guarantee exceptional performance.
