Diamond Eye CLAMP Band 4in METRIC HARDWARE AL

Exhaust clamps, hose clamps, and line clamps are the small hardware that keeps performance systems sealed and rattle-free. Whether you are finishing an exhaust build, routing coolant lines, or securing boost piping on a turbocharged engine, the right clamp makes the difference between a clean install and a leak.Popular UpgradesBand clamps and slip-fit exhaust clamps are the most popular choice for performance exhaust work, providing a tight seal without crushing the pipe. T-bolt clamps are preferred for silicone couplers on intercooler and intake piping where high boost pressure demands extra clamping force. Stainless steel construction is standard on quality performance clamps for corrosion resistance under heat cycling.What clamps work best for exhaust connections?Lap-joint exhaust clamps and two-bolt band clamps are the most common choices for slip-fit exhaust connections. For a cleaner look with leak-free performance, v-band clamps paired with matching flanges offer the best res...

Diamond Eye Performance manufactures mandrel-bent exhaust systems and components for diesel trucks, with a catalog that spans DPF-back, turbo-back, and cat-back exhaust for Cummins, Duramax, and Power Stroke platforms. CNC mandrel bending maintains full internal tube diameter through bends from 3/8-inch to 5-inch OD in both aluminized and stainless steel, ensuring exhaust gas flow is not restricted by collapsed bends common in lesser exhaust systems.Popular UpgradesDiamond Eye 4-inch DPF-back exhaust systems for the Cummins 6.7L and Duramax 6.6L diesel trucks are the most popular products, providing a meaningful reduction in exhaust restriction over the factory 3.5-inch outlet section. Stainless steel mandrel-bent kits are available for the Ram 2500, Ram 3500, Ford Super Duty, and GM HD truck platforms with direct-fit connections and tip options. Aluminized exhaust kits offer the same mandrel-bent quality at a lower price point for builds in drier climates where corrosion is less of...

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...
