2-1 S.S. Merge Collector s 1.625in Inlet ID 2in

The 2-1 S.S. Merge Collector with 1.625in Inlet ID and 2in outlet is a premium stainless steel exhaust component designed for high-performance engine builds and custom intake manifold configurations. This merge collector consolidates multiple runner paths into a single primary pipe, making it essential for naturally aspirated and turbocharged applications that seek improved scavenging and flow efficiency.

Constructed from mandrel-bent stainless steel, the 2-1 merge collector features a single 1.625-inch inlet that merges smoothly into a 2-inch primary outlet, minimizing turbulence and exhaust gas reversion at the merge point. The stainless steel construction resists corrosion and heat cycling fatigue, ensuring longevity in high-temperature engine bay environments where mild steel would degrade or warp over time.

This merge collector is ideal for builders constructing custom dual-runner exhaust systems, providing a reliable solution for optimizing exhaust flow. Its compact 7 x 4.8 x 9.6-inch footprint and light 1.75-pound weight make installation and fitment verification straightforward during custom header or manifold assembly.
