    Product Details

    Mid-Length Tube Mid-Length Tube Exhaust Header by Doug's Headers®. Color: Silver. Header Style: Mid-Length 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.

    I'm restoring my 1963 Mercury Meteor. Headers fit great, look killer. The car pulls so much better off the line now. Not the easiest install but totally worth it.
