4-1 Merge Collector 2.5in Inlet ID 4in Out

The Vibrant Performance 4-1 Merge Collector 2.5in Inlet ID 4in Out is an essential component for fabricators and racers aiming to enhance exhaust gas scavenging in high-performance header builds. This slip-on collector is designed for those looking to optimize volumetric efficiency, making it suitable for both custom turbo manifolds and naturally aspirated competition headers.

Constructed from durable stainless steel with a natural finish, this merge collector features a 4 into 1 configuration that accepts 2.5-inch primary tubes. The 4-inch outlet diameter allows for high-flow requirements, reducing backpressure and improving overall power output across the RPM range. The slip-on design facilitates thermal expansion and easier servicing compared to fully welded structures.

This 10324 model is ideal for custom exhaust projects where precision fitment and long-term durability are crucial for the end user. By allowing modular purchasing for V8 headers, it caters to builders who prioritize flexibility in their exhaust system designs.
