Product Description

Doug's Headers Black Coated 2" Long Tube Headers for 1967, 1968, 1969, and 1970 Mustangs with a 390 or 428 Engine.

Made of heavy 16 gauge tubing, these 2" Long Tube Headers (D627-B) offer long-lasting performance on 1967-1970 Mustangs with a 390 or 428 Engine. Manufactured by Doug's Headers, each Long Tube Header is coated in a hi-temp black finish for stealth and durability. Once installed, enjoy a reduction in backpressure and higher RPM horsepower. 

Features and Benefits:
- 3/8” Thick Machined Flanges Means No Warping
- CNC Mandrel Bent Tubes for an Accurate Fit and Better Flow
- Precision Formed Long Transition Collectors and Long Tube Design 
- Heavy 16 Gauge Tubing for Extended Part Life
- Tubes Are Pre-polished to Remove Scratches
- Hi-Temp Black Coated Headers 

During development and manufacturing, Doug's designs, fits, and re-checks the Long Tube Headers on the 1967-1970 Mustang multiple times and at various stages. It's a thorough, arduous process that distinguishes Doug's from the competition, who tend to value low costs over high quality. 

Doug's expels all the exhaust from each cylinder on your 390 or 428 engine by tuning each header with the proper tube size and length. This reduces pumping losses for a dramatic increase in horsepower and torque.
