Header development and design is complex and requires a substantial amount of time and resources to do the job right! 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.
- Thick flanges (3/8 inch to 5/8 inch) with no warping
- CNC mandrel bent tubes for an accurate fit and a better flow
- Precision formed long transition collectors that reduces backpressure
- Heavy gauge tubing (16 and 14G) for longer life
- Header tubes are pre-polished for a better appearance
