Description

Flowtech Lakester headers deliver classic styling taken from the early dry lake and Bonneville speed racers--perfect for vintage lake-style street rods. They feature high-low, mandrel-bent tubes to provide consistent diameters for smooth flow and increased exhaust velocity. The heavy-duty tubing and high-quality welds guarantee strength and durability. Smooth-transition, 1 5/8 in. diameter primary tubes are used for better exhaust flow--optimizing performance and throttle response, as well as broadening the torque curve. The long-transition velocity collector connects to an undercar exhaust, and the block-off plate can be removed for maximum sound output. The Flowtech Lakester Street Rod headers are TIG-welded, with machined 3/8 in. flanges for a strong, leak-free seal. They also include premium aluminum header gaskets and installation hardware.
