Box of Bends 1.625in

The SCHOENFELD Box of Bends 1.625in Exhaust Pipe Bend Kit (Part Number MB162) delivers a comprehensive solution for custom exhaust fabrication and high-performance exhaust system construction. This 1.625-inch diameter mandrel bend kit contains approximately 36 feet of 18-gauge steel tubing in a variety of bend angles and straight sections, enabling builders to design and assemble exhaust systems tailored to specific engine bay layouts and performance requirements without excessive welding or secondary bending operations.

The 1.625-inch tube diameter sits in the optimal flow range for small-block and mid-sized engine platforms, balancing scavenging efficiency with backpressure management across the mid-range RPM band. The 18-gauge steel construction provides structural integrity while remaining workable for flanging, porting, and TIG welding. Mandrel-bent sections maintain consistent wall thickness through each bend radius, eliminating kinks and flow restrictions that plague sharp or crush-bent tubing. The assorted bend collection—including common angles like 45-degree, 90-degree, and U-bends alongside straight sections—reduces fabrication time and minimizes custom bending costs for shops and serious DIY builders.

This kit serves engine builders, exhaust fabricators, and performance shops constructing headers, mid-pipes, and cat-back systems for street cars, track vehicles, and engine swaps where OEM exhaust routing doesn't fit the modified engine or bay configuration. The pre-bent inventory accelerates prototype development and reduces labor hours on custom builds. Welders and fabricators value Schoenfeld's bend quality for repeatability across multiple jobs and the elimination of scrap from unsuccessful field bends.
