Product Highlights

Anatomy of a Doug's Header
Header development and design is complex and requires a substantial amount of time and resources to ensure the job is done right. Many manufacturers are unwilling to make the commitment and instead offer lower quality headers at cheap prices. Doug's does not compromise performance, quality or fit to compete with those inferior designs. Each Doug's Header is designed with the proper tube size and length to efficiently scavenge the exhaust from each cylinder, reducing pumping losses resulting in maximum increases in horsepower and torque.
