Stainless steel pipe segment for custom-built exhaust systems, downpipes, charge pipes, and coolant lines BOOST products Stainless Steel Pie Cut with Spigot Male Segment 42.4mm x 1.5 90° pie cut interlocking start segment type – norm 2 - radius R32 - 15° segment - 1.4301 stainless steel Stainless steel pipe segment for custom-built exhaust systems, downpipes, charge pipes, and coolant lines The latest technology in Pie Cut fabrication! Forget tedious marking, angle measuring, and manual cutting – these precision Pie Cuts make it effortless! Precisely engineered start and end segments for pie-cut bends: one side is smooth for connection to a straight pipe, while the other side features male spigots for a perfect, interlocking alignment to the next segment. Ideal for clean, repeatable weld joints in exhaust, intercooler, and intake systems. The tab design ensures quick alignment without jigs, minimizes gaps, and improves weld appearance – perfect for TIG welders, prototype builders, and professional fabricators. Features: One smooth side and one male spigot side – ideal for starting or finishing a pie-cut bend with spigots Interlocking fit: reduced gaps and less post-processing Weld-ready: deburred, clean-cut, and oil-free Compatible with our other tabbed Pie Cuts of the same size Suitable for TIG/MIG welding; TIG recommended for the highest quality Processing Advantages: Quick, precise positioning thanks to the spigot alignment system Stable tack-welding – reduced distortion during final welding Clean internal contour for optimal flow Professional weld finish without step formation Types & Applications: Start Piece: Smooth side connects to pipe or straight section, interlock/male (spigot) side to the first segment group End Piece: Female (spigot recess) side connects to the last segment, smooth side to outlet or end pipe Suitable for exhaust systems, charge pipes, intake and cooling systems Welding Instructions: Degrease and deburr mating surfaces, check fitment before welding Tack-weld all around, then perform full circumferential welding For best appearance and internal quality: use moderate heat control and proper back purging Material & Specifications: Material: 1.4301 Stainless Steel – corrosion- and heat-resistant Size: 42.4 mm Wall Thickness: 1.5 mm Angle: 15° Radius: Norm 2 – Radius R32 Manufacturing tolerances matched to our tabbed segment series *We can also supply Spigot Pie Cuts with 9° or 12° cuts on request (minimum order quantity: 50 pieces per size). Scope of Delivery: 1× Pie Cut with Spigot Start / End Piece 42.4mm x 1.5 – Norm 2 – Radius R32 – 15° Segment – 1.4301 Stainless Steel Additional tabbed Pie Cuts are available in our shop – for complete segmented bends.
