Product Description

Dougs Headers Ceramic Tri-Y Headers for all 1965, 1966, 1967, 1968, 1969 and 1970 Mustangs with an Automatic Transmission and a 260, 289 or 302 Engine.

These headers have a 1-5/8" to 2" primaries that go into 2.5" collectors.

Every header from Dougs Headers 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. Dougs Headers are carefully developed for 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 headers come with all the necessary mounting hardware, collector reducers, premium gaskets and detailed installation instruction sheets. Our extra thick gaskets are rated up to 1100F, pressures to 3700 psig (255 bar), and are designed for an exact port match with Dougs Headers.

Metallic Ceramic Thermal Barrier Coating (MCTBC) is simply the best header finish on the market and comes standard on all Dougs 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.

Dougs Headers Tri-Y Ceramic Automatic 260/289/302 1965-1970 is rated 4.0 out of 5 by 1.
Rated 4 out of 5 by from Looks real clean. I bought these headers a while back when I was planning a rebuild. I finally got these put in, and it was a perfect fit. I undid the motor mounts lifted the engine and they dropped right in. I gave these headers four stars for, fit, looks, and ease of installation. I haven't heard them yet, still assembling engine bay.
