Fupower Factory Tour | Precision Pie Cut & TIG Welding for Exhaust Piping
By FeliciaJune 3rd, 202639 views
Pie cut construction is widely used for tight-radius exhaust bends, which cannot be completed by regular mandrel pipe bending. Our experienced fabricators cut stainless steel tubing into segmented pie slices first, align every piece precisely for seamless matching, then carry out high-standard TIG welding to connect each segment into smooth 90°, 45° or custom angled exhaust elbows.
Every weld is carefully executed by our skilled welder with professional welding torches and strict operating standards. TIG welding delivers neat, full-penetration weld seams without pinholes or gaps, ensuring the finished elbow is airtight, leak-proof and capable of enduring long-term high exhaust temperature and vibration under daily driving or track racing conditions. After welding, parts go through polishing treatment to get the shiny mirror finish you see on our finished stainless steel exhaust pipes.
Pie cut custom welding gives us extreme flexibility for bespoke exhaust projects. Whether customers need rare custom bend angles for engine swap builds, tight-clearance race exhaust or model-specific aftermarket exhaust kits, our pie-cut welding workshop can tailor every elbow exactly to client drawings and installation requirements. Combined with our in-house cutting and bending capacity, this handmade craft is key to supporting our full OEM & ODM customization service for global automotive modification clients.
All our pie-cut elbows are available in SS304 stainless steel, titanium and aluminum materials to match different budget and performance needs for street cars, sports cars and racing vehicles.
