3-1 Merge Collector ID 1.625in Inlet/2.5in Out

The 3-1 Merge Collector ID 1.625in Inlet/2.5in Out from VIBRANT PERFORMANCE is a precision exhaust manifold component designed for builders focused on efficient cylinder scavenging and reliable flow characteristics. This merge collector is essential for creating a cohesive exhaust system that maximizes horsepower and torque across various engine builds, including custom street engines and race applications.

Engineered with a 1.625-inch inlet diameter per primary runner and a 2.5-inch outlet diameter, this collector promotes smooth gas transition and minimizes turbulence at the merge point. Its stepped design prevents dead zones and exhaust reversion, ensuring consistent scavenging efficiency during rapid throttle transitions. Constructed from durable materials, the collector is built to withstand high-temperature cycles without warping or cracking.

Fabricators and engine builders will find this merge collector beneficial for optimizing exhaust gas velocity and reducing backpressure, making it ideal for performance applications. Its geometry works in concert with header tube sizing to create backpressure sweet spots that enhance low-end torque while sustaining mid and top-end power. This collector is a vital component for anyone looking to enhance their engine's performance.
