    Doug's CORVETTE SIDEMOUNT HEADERS ChromeHeader 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 re-checked numerous times during the design and manufacturing process.

    • 3/8" thick flanges with machined sealing beads...no leak performance
    • CNC mandrel bent tubes... accurate fit & better flow
    • Precision formed long transition collectors and long tube design... reduces backpressure and increases higher RPM horsepower
    • Heavy 16 gauge tubing... longer life
    • Header primaries, collectors and flanges are pre-polished to remove scratches before chrome is applied for that show quality appearance
