Detailed Description
Doug's PASSENGER CAR HEADERS Long Tube High Temperature Black Coated development and design is complex and requires a substantial amount of time and resources to do the job right! Many manufacturers are unwilling to make the commitment and instead offer compromised headers at lower prices. Doug's will not compromise performance, quality or fit to compete with inferior designs at cheap prices. 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 rechecked numerous times during the design and manufacturing process.
- 3/8 inch thick machined flanges - no warping
- CNC mandrel bent tubes - accurate fit and better flow
- Precision formed long transition collectors and long tube design - reduces backpressure and increases higher RPM horsepower
- Heavy 16 gauge tubing - longer life
- Tubes are pre-polished to remove scratches and the header is finished with a High Temperature Black Coating.
