The Vibrant Performance 4-1 S.S Merge Collectors 2.25in Inlet ID 4in outlet is a premium stainless steel exhaust manifold designed for engine builders and performance enthusiasts who demand efficient scavenging and quality construction. This merge collector consolidates four individual runner tubes into a single outlet, making it an essential component for any turbo or naturally aspirated engine swap where header-to-downpipe transition is critical.
Constructed from mandrel-bent stainless steel tubing, the 4-1 merge collector features a design that enhances exhaust flow. The 2.25-inch inlet diameter on each of the four runners accommodates standard high-flow headers, while the consolidated outlet provides a smooth transition for turbochargers, wastegates, or direct downpipe connections. Stainless steel construction resists corrosion and thermal stress better than mild steel alternatives, extending component lifespan under extreme underhood temperatures.
This merge collector is ideal for builders upgrading four-cylinder engines with turbocharger kits, LS swaps into compact chassis, or any custom builds where space is limited. Weighing just 3.55 lbs and featuring a compact footprint of 6.6 x 6.4 x 12.1 inches, it allows for flexible engine bay packaging, making it a versatile choice for performance applications.
