2-3/8in x 4-1/2in Merge Collector

The DYNATECH 2-3/8in x 4-1/2in Merge Collector is a slip-on exhaust manifold component designed for custom automotive builds and performance engine modifications. This product is ideal for builders and mechanics aiming to enhance exhaust scavenging and flow dynamics in their vehicles. It serves as a crucial junction where individual cylinder runners converge into a single exhaust pipe, making it suitable for various applications including street machines and race engines.

This merge collector features a 2-3/8-inch inlet diameter and a 4-1/2-inch outlet dimension, optimized for mid-range displacement engines and street performance applications. The design minimizes exhaust turbulence by blending multiple runner streams into a unified flow path, which helps reduce backpressure while maintaining exhaust velocity. Weighing 4.8 lbs and measuring 17.45 inches in length, it integrates seamlessly into custom header and exhaust system builds.

Engine builders and fabricators will find this merge collector particularly beneficial when constructing stepped or tri-y headers for V-6, small-block V-8, or turbocharged platforms that require precise tuning. The straightforward installation process allows for TIG-welded connections to individual primary tubes, ensuring a reliable and efficient exhaust system.
