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
