Product DescriptionDoug's Headers Ceramic Tri-Y Headers for 1964-1970 Automatic Mustangs with a 260, 289 or 302.
These headers have a 1-5/8" to 2" primaries that go into 2.5" collectors.
Every Doug’s header is tuned with the proper tube size and length to efficiently remove all the exhaust from each cylinder, reducing pumping losses resulting in a dramatic increases in horsepower and torque. Doug’s headers are carefully developed on the vehicles they are intended to fit and are re-checked numerous times during the design and manufacturing process.
Tri-Y headers yield maximum power from off idle to 4500 RPM, making them well suited for maximum mid-range torque.
These Doug’s headers comes with all the necessary mounting hardware, collector reducers, premium gaskets and detailed installation instruction sheets. Our extra thick gaskets are rated up to 1100ºF, pressures to 3700 psig (255 bar), and are designed for an exact port match with Doug’s headers.
Metallic Ceramic Thermal Barrier Coating (MCTBC) is simply the best header finish on the market and comes standard on all Doug’s headers. MCTBC protects and extends the life of headers by creating a thermal barrier that significantly lowers underhood temperatures and protects the substrate metal from thermal fatigue. After MCTBC is applied, it is polished with a vibratory finishing process that produces a high luster aluminum appearance. This coating is easy to maintain and will last for years under normal operating conditions. The polishing process compresses and activates the coating, which increases the surface hardness to produce a finish that is 60% more corrosion resistant than an unpolished surface.
