The 1-5/8 inch primary tubes are precision mandrel-bent to optimize exhaust flow and ensure an accurate fit. The headers feature robust 3/8 inch thick machined flanges designed to prevent warping under extreme heat, and a 3-inch collector with included 2.500 inch exit reducers. Doug's Headers are renowned for providing significant increases in horsepower and torque across the entire RPM spectrum.
