Fabrication
Fabrication parts and materials provide the raw components needed to build, repair, and modify custom exhaust systems, turbocharger plumbing, intercooler piping, fuel system lines, oil routing, and engine bay heat management on performance and competition vehicles. Stainless steel tubing, titanium tubing, aluminum charge piping, mandrel bends, pie cuts, flanges, merge collectors, V-band clamps, O2 sensor bungs, AN fittings, PTFE hose kits, braided fuel and oil lines, heat shields, and welding supplies are the backbone of any serious custom fabrication project. Professional fabricators, race team mechanics, and advanced DIY builders who want full control over exhaust routing, charge pipe layout, or fuel system plumbing choose raw fabrication materials rather than pre-bent kits because custom fabrication allows fitment solutions that no universal kit can accommodate. Brands including Vibrant Performance, Ticon Industries, Stainless Bros, Radium Engineering, Fragola, and DEI provide th...
