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

The Cast 2 into 1 Y-Collector 3in Inlet 2.5in Outlet from Vibrant Performance is designed for builders looking to enhance exhaust manifold designs and optimize underhood space. This collector merges dual exhaust runners into a single 2.5-inch outlet, making it suitable for custom engine builds, turbo conversions, and performance street cars.

The collector features a 3-inch inlet and a tapered 2.5-inch outlet, which helps reduce turbulence at the merge point, enhancing scavenging efficiency and exhaust velocity. Its cast iron construction offers superior thermal mass compared to welded steel, which helps minimize thermal cycling stress and prolongs component life in high-temperature environments.

Ideal for mechanics and fabricators, this Y-collector is particularly favored for LS swaps, small-block Chevy builds, and custom platform conversions where OEM manifolds may be restrictive. Its compact footprint and lightweight design allow for easy installation in tight engine bays without compromising durability or exhaust flow characteristics.
