Vibrant 4-1 SS Merge Collector (2in Inlet Slipover ID 3-1/2in Merge Outlet OD)
Vibrant Performance 4-1 Merge Collectors feature a single slip design ideal for naturally aspirated applications, constructed from precise cut mandrel-bent 304 stainless steel tubing with high-quality TIG welded construction. The expanded inlet on this Vibrant 10309 model is designed to slip over 2" OD piping for a secure, leak-free fit, while the 3-1/2" merge outlet OD provides smooth exhaust flow transition. Sold individually, this collector merges four 2" inlets into a single 3-1/2" outlet, optimizing exhaust scavenging and velocity for improved horsepower and torque in custom header builds. Perfect for high-performance naturally aspirated or mild boosted setups where precise merge geometry and stainless durability are critical. TIG welds ensure strength and clean appearance under the hood or chassis.

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...
