Doug's 65-70 Mustang SBF Tri Y Stainless (1964-1970 Mustang , Cougar) - D690YA-SS
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.

Since 1958, the Original Doug's Headers has been an industry leader in the Muscle Car Performance Header business. Top Name Drag Race cars across the nation proudly wore the Doug's Logo and Performance & Truck Enthusiasts followed suit making Doug's a formidable brand in the marketplace. In 2005, Doug decided to retire, and the company became a natural fit for PerTronix alongside our other Performance Brands. Doug's Headers had always prided themselves on fit and quality that were second to none. PerTronix has honored this philosophy over the years, continuing to expand R&D resources to meet the needs of the market and our customers.
