If there has ever been a more BangShift approved product released by a high performance aftermarket company, we’re not sure what it is. While you are looking at the new upright header offerings from Flowtech, you are actually looking at more than that. You are looking at a product success story that came from within the company. One of their employees is a hardcore demolition derby guy and he effectively pitched the idea to the company brass and here we are.

If you are thinking that these are a niche product and a weird thing to be promoting, you’d be wrong. There are thousands and thousands of cars and trucks running upright headers in multiple forms of motorsports and other fun activities. How many videos have we run of pulling trucks, mega trucks in the muck, and demolition derby runners to name a few over the years? A ton!

In typical Flowtech fashion, these are mandrel bent, they have a thick 3/8″ flange, they have a great collector design, and they are offered in two primary sizes depending on your engine needs. Right now the headers are being offered for small block Chevy engines only. We’ll see what happens with offerings going forward.

Here’s the full release from Flowtech –

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.
