Box of Bends 1.750in

The Schoenfeld Box of Bends 1.750in exhaust pipe bend kit is a comprehensive mandrel bending solution for custom exhaust system fabrication and modification. This 36-foot assortment includes various pre-formed bends and straight sections in 1.75-inch diameter, engineered from 18-gauge steel tubing to deliver the precision geometry required for tight-tolerance exhaust routing in performance engine builds and vehicle customization projects.

The kit's mandrel-bent construction maintains consistent wall thickness and interior diameter throughout each bend radius, preventing flow restrictions and turbulence that compromise scavenging efficiency. At 18-gauge thickness, the tubing balances durability with weight savings while resisting thermal warping under sustained exhaust temperatures. The 1.75-inch diameter specification matches common primary collector sizes in small-block and mid-sized V8 applications, making this kit suitable for street performance, racing, and vintage restoration work. The included variety of bend angles and straight sections eliminates the need for multiple fabrication passes and reduces cutting waste during system design and mockup.

This kit targets fabricators, performance shops, and enthusiasts building custom exhaust systems who require proven mandrel-bent tubing components. The extensive linear footage and assorted bend angles accelerate prototype development and system fitting without delays for special orders. Steel composition allows full welding capability for permanent assembly or TIG repair, and the pre-formed geometry reduces labor time during header construction and exhaust routing optimization.

Mandrel-bent exhaust systems are industry standard for performance applications because they preserve volumetric flow and minimize backpressure spikes. Schoenfeld's tubing maintains this standard through strict bend radius control and material consistency, supporting both street efficiency and high-RPM power delivery across diverse engine platforms.
