Cast 2 into 1 Y-Collecto r 3in Inlet 2.5in Outlet

The Cast 2 into 1 Y-Collector 3in Inlet 2.5in Outlet by Vibrant Performance is a precision exhaust manifold designed to consolidate dual primary pipes into a single collector tube, making it an essential component for custom exhaust builds on performance vehicles. This cast collector serves as the transition point where two exhaust runners merge before flowing into your secondary piping, cat-back system, or resonator. Whether you're building a street engine, track car, or restoring a classic with modern performance aspirations, this Y-collector enables seamless exhaust scavenging while maintaining optimal flow dynamics.

Manufactured from durable cast material, this collector features a 3-inch dual inlet design that accepts two separate primary tubes and transitions smoothly into a 2.5-inch outlet for reduced turbulence and improved exhaust velocity. The casting process ensures structural integrity and thermal stability under high-temperature exhaust gas exposure, while the stepped diameter design manages the merging of exhaust pulses to minimize backpressure and reversion. Weighing just 1 pound, the compact 4.9 x 3.8 x 4.9-inch form factor fits tight engine bays without sacrificing durability or performance characteristics that serious tuners demand.

Mechanics and enthusiasts choose this Y-collector when upgrading manifolds, installing headers on previously carbureted engines, or transitioning from factory exhaust to a custom system. Installation requires proper fitment verification with your specific inlet pipe diameter and outlet flange configuration; confirm your primary tube ID matches the 3-inch inlet specification and that your secondary piping accepts the 2.5-inch outlet diameter. This collector pairs well with aftermarket mufflers, resonators, and cat-back systems, and its compact design allows flexibility in exhaust routing even on vehicles with tight underbody clearance.
