Flowtech is proud to announce their all-new Small Block Chevy Upright headers. These headers were developed with demolition-derby, mud truck and truck pulling competition in mind.
This distinctive new design is available in a natural finish in two tube diameters (1-5/8” or 1-3/4”), and both are designed specifically for Small Block Chevys – especially big-cubic-inch Small Block Chevys. Both sizes also feature CNC-mandrel-bent tubes and consistent tubing diameters that optimize exhaust flow, cylinder-scavenging, and overall engine performance.
Flowtech Upright Header collectors are three inches in diameter and 12 inches long. Inside these "merged" collectors are welded-in spears that promote exhaust flow and reduce exhaust gas re-entry into the primary tubes, helping the engine "breathe" easier and more efficiently.
Manufactured from heavy-duty 16-gauge 409 stainless steel tubing for eye-catching looks, greater durability, and more corrosion-resistance, Flowtech Upright Headers have extra-thick CNC-machined header flanges for maximum strength, a leak-free seal, and a perfect fit every time.
