The expanded inlet on this \u003cstrong\u003eVibrant 10309\u003c\/strong\u003e 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.\u003c\/p\u003e\n\u003ch4\u003eKey Features \u0026amp; Benefits\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e304 Stainless Steel Tubing – Corrosion-resistant and durable for long-term performance\u003c\/li\u003e\n\u003cli\u003eMandrel-Bent \u0026amp; TIG Welded – Smooth flow with precise construction for maximum scavenging\u003c\/li\u003e\n\u003cli\u003e2\" Inlet Slipover ID – Fits directly over 2\" OD piping for easy, secure assembly\u003c\/li\u003e\n\u003cli\u003e3-1\/2\" Merge Outlet OD – Optimized transition for improved exhaust velocity and power\u003c\/li\u003e\n\u003cli\u003eVibrant Quality – Precision engineering trusted in motorsports and custom builds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ctable width=\"100%\" cellspacing=\"0\" cellpadding=\"8\" border=\"1\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003e10309\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eVibrant Performance\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003e4-1 Merge Collector\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003e304 Stainless Steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInlet Size\u003c\/td\u003e\n\u003ctd\u003e2\" OD slipover (4 inlets)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutlet Size\u003c\/td\u003e\n\u003ctd\u003e3-1\/2\" OD merge\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDesign\u003c\/td\u003e\n\u003ctd\u003eSingle slip, mandrel-bent, TIG welded\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eQuantity\u003c\/td\u003e\n\u003ctd\u003eSold individually\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch4\u003eWhats Included\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eOne 4-1 merge collector (2\" inlet slipover to 3-1\/2\" outlet)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eProduct Notes\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eOptimized for naturally aspirated applications; excellent scavenging and flow\u003c\/li\u003e\n\u003cli\u003eSlipover inlet fits over 2\" OD piping ideal for custom header collectors\u003c\/li\u003e\n\u003cli\u003eTIG welds provide strength and clean appearance for exposed installations\u003c\/li\u003e\n\u003cli\u003e3-1\/2\" merge outlet transitions smoothly to larger downpipe or exhaust\u003c\/li\u003e\n\u003cli\u003eVibrant Performance trusted in racing and custom exhaust fabrication\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eEstimated time: Varies (custom welding\/fabrication required)\u003c\/li\u003e\n\u003cli\u003eSlip inlet over 2\" OD piping and weld or clamp securely\u003c\/li\u003e\n\u003cli\u003eAlign merge outlet with downpipe\/exhaust tubing\u003c\/li\u003e\n\u003cli\u003eTIG weld for permanent, leak-free connection\u003c\/li\u003e\n\u003cli\u003eProfessional fabrication\/welding recommended for best results\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eThis Part Fits\u003c\/h4\u003e\n\u003ctable cellspacing=\"0\" cellpadding=\"8\" border=\"1\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eYear Range\u003c\/th\u003e\n\u003cth\u003eMake\u003c\/th\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003cth\u003eEngine\u003c\/th\u003e\n\u003cth\u003eNotes\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eUniversal\u003c\/td\u003e\n\u003ctd\u003eUniversal\u003c\/td\u003e\n\u003ctd\u003eUniversal\u003c\/td\u003e\n\u003ctd\u003eUniversal\u003c\/td\u003e\n\u003ctd\u003eCustom exhaust\/header builds; 2\" inlet slipover to 3-1\/2\" outlet merge\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch4\u003eWhy Choose Vibrant 4-1 Merge Collectors?\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003ePrecision mandrel-bent 304 stainless for smooth, high-flow performance\u003c\/li\u003e\n\u003cli\u003eSlipover design simplifies custom header fabrication\u003c\/li\u003e\n\u003cli\u003eTIG welded construction ensures strength and clean welds\u003c\/li\u003e\n\u003cli\u003eVibrant Performance leading brand in exhaust components and fittings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cstrong\u003eFrequently Asked Questions\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eQ:\u003c\/strong\u003e Is this collector for naturally aspirated or turbo?
