The Aeroflow Merge Collector 2 into 1 is designed to simplify turbo manifold fabrication for Mazda rotary applications. Cast as a single piece for strength and consistency, this collector helps reduce fabrication time while delivering a smooth transition from dual pipes into a single turbo inlet. It is an ideal solution for custom manifold builds where reliable exhaust flow is essential.

Featuring a 2-1/8" tube size and a T4 flange, this merge collector is well suited to 12A and 13B 2 rotor rotary engines. The one piece cast construction helps eliminate the risk of cracks or defects commonly associated with fabricated weld assemblies, making it a durable choice for demanding turbo setups. It is designed for builders who want a professional result without the trial and error of hand shaping a collector.
