Stainless steel pipe segment for custom-built exhaust systems, downpipes, charge pipes, and coolant lines BOOST products Stainless Steel Pie Cut with Spigot Female Segment 89mm x 1.5 90° pie cut interlocking end segment type – norm 2 - radius R76 - 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 female spigots for a perfect, interlocking alignment to the next segment. Ideal for clean, repeatable weld joints in exhaust, intercooler, and intake systems. The interlock/spigot 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 female spigot side – ideal for finishing or starting 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 spigot/ interlock 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: 89 mm Wall Thickness: 1.5 mm Angle: 15° Radius: Norm 2 – Radius 76 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 Female (End) Piece 89m x 1.5 – Norm 2 – Radius R76 – 15° Segment – 1.4301 Stainless Steel Additional tabbed Pie Cuts are available in our shop – for complete segmented bends.
