[More Info]
Doug's is the pioneering force behind the popular TRI-Y design for cars and trucks. The unique, shortend, paired primary tubes increase mid-range torque without sacrificing top end power. TRI-Y's are a great choice for daily drivers and heavy duty trucks looking to increase power from idle up to 4500 RPM while maintaining maximum fuel efficiency.
Features:
  • 3/8" thick machined flanges to prevent warping
  • CNC mandrel bent tubes ensure accurate fit and better flow
  • Heavy 16-guage tubing for longer life
  • Tubes are pre-polished to removed scratches before applying metallic ceramic or hi-temp black coating
