Product Details

4-Tube Steel Metallic Ceramic Coated Short Tube Exhaust Headers (D306) by Doug's Headers®. Primary Tubing Diameter: 1.75". Collector Outlet Diameter: 3". Color: Silver. Header Coating: Ceramic. Header Style: Short Tube. 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. 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.

Doug's Headers are ideal for muscle cars, street rods, and race cars, as well as trucks, SUVs, and motorhomes. With more than 50 years of experience, Doug's Headers is a name you can trust for superior quality and fit. Doug has been elected to five different drag racing halls of fame and is truly a pioneer in the manufacturing of high performance exhaust systems!

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.
