    Doug Headers

    Chevy Impala 1967, 4-Tube Steel Short Tube Exhaust Headers by Doug's Headers®. Primary Tubing Diameter: 1.75". Collector Outlet Diameter: 3". Emissions: Racing Only. Header Style: Short Tube. Doug's Headers 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.
