The Story
Highlights
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.
- 3/8” thick machined flanges to prevent warping
- CNC mandrel bent tubes for an accurate fit and improved flow
- Durable 16 gauge tubing
- 1 5/8" Primary Tubing Diameter
- 2.5" Collector Port Diameter
- Oval Port Shape
- Metallic Ceramic Coating
Our Metallic Ceramic Coating protects and extends the life of headers by creating a thermal barrier which significantly lowers under hood temperatures and protects the substrate metal from thermal fatigue. After the Metallic Ceramic Coating is applied, it is polished with a vibratory finishing process that produces a high luster aluminum appearance. The polishing process compresses and activates the coating, creating a surface which is harder and 60% more corrosion resistant than an unpolished surface.
