Overall Assessment

Customers praise the Schoenfeld Headers for their excellent angles and superior fit compared to competitors like the Speedway Fat Fenders. Noted features include how the front two tubes wrap over the cylinders, creating valuable space between the tires' inner rear edge and the header - about 6"-7". This design offers better placement for vehicle setups, like a '47 Dodge with a 350 on an S-10 chassis. Their one bend construction, ending straight out, contrasts favorably to the 3 bends of fat fenders. Overall, customers consider them a quality, value-for-money purchase, likely to buy again.

Headers are great, the angles are much better for my setup then the speedway fat fenders. The fat fenders brought the tubes too close-within an inch of my tire. These schoenfeld headers bring the tubes back closer to the firewall because the front two tubes (cylinder 1 and 2) wrap over the (3 and 4) cylinders and run out near the rear of the stack. This creates more space between the front tube and the tires inner rear edge. I have about 6"-7" from tire to header. My truck is a '47 dodge with a 350 sitting on mid '90's s-10 chassis. The front wheels center is approximately lined up with the front of cylinder 4. Wheels are 15". These schoenfeld's only have 1 bend and they end pointing straight out of the vehicles side. The fat fenders have 3 bends and the fat fenders last bend points parallel with the frame.
