Product Description

Dougs Headers Ceramic 1-5/8"-2" Stepped Design Tri-Y Headers for all 1965, 1966, 1967, 1968, 1969 and 1970 Mustangs with a Manual Transmission and a 260, 289 or 302 Engine.

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.

*Installation may require use of a Non-HiPo 1965-1966 equalizer bar.
*These headers have a 1-5/8" to 2" primaries that go into 2.5" collectors.

These Dougs Headers come with all the necessary mounting hardware, collector reducers, premium gaskets and detailed installation instruction sheets. These 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.

*1965-1968 Mustangs equipped with power steering require a slave cylinder lowering bracket (SCB).

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.

Product Questions

On 1966 Hi Po cars, the header description says to use the non-Hi Po equalizer bar. However, the description for the non-Hi Po equalizer bar says it will not fit the Hi Po cars. This doesn't make sense to me. Help.

Asked by: 409gary
To the best of our knowledge, the only difference with the Hi Po version is that it has been strengthen with gussets as well as having a different bend on one of the arms to clear the factory Hi Po exhaust manifolds. So if you are replacing with our headers, this should not an issue. Please contact our customer support if you have any other questions. Best Regards, Doug's!
