Elbow Kit

The HOWE Elbow Kit (model H2100) is a mandrel-bent exhaust pipe bend kit engineered for custom exhaust fabrication, routing, and high-performance system design. This kit addresses a critical need for serious fabricators and engine builders who require precision bends without kinks, flow restriction, or wall thinning—common problems when using standard tube benders on thin-wall tubing. Whether you're building a turbo manifold, intercooler piping, or multi-bend exhaust systems, mandrel bending preserves internal diameter consistency and maintains structural integrity under thermal and pressure cycles.

This elbow kit contains one expanded-end elbow (allowing welded or slip-fit connection) and two additional elbows with preset bend angles—one 45-degree and two 20-degree bends—all in 3.5-inch diameter 18-gauge steel construction. The mandrel-bent design ensures smooth, consistent bend radii that eliminate turbulence and maintain exhaust flow velocity, critical for turbo spool response and exhaust scavenging efficiency. The natural steel finish resists oxidation better than bare iron and can be ceramic coated or wrapped for thermal management. At 6.8 lbs, the kit is compact enough for bench work while delivering production-quality results.

Professional fabricators, turbo shops, and street rod builders benefit most from this kit when assembling custom exhaust systems, intercooler charge piping, or intake manifold runners where OEM bends don't fit the application. The 3.5-inch diameter suits modern turbocharged and supercharged engines requiring high flow capacity. Installation involves welding or flanging the expanded end to your manifold or primary pipes, then utilizing the preset bends to route around engine bay obstacles. Compatibility depends on your specific piping diameter and flange pattern, so measure twice before ordering; this kit's bent sections cannot be re-bent without professional equipment.
