Product Details
4-Tube Hi-Temp Black Coated Short Tube Exhaust Headers (D337-B) by Doug's Headers®. Primary Tubing Diameter: 1.75". Color: Black. Header Coating: Ceramic. 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.
