Stainless Headers Mfg, Inc. - 321 Stainless Steel Merge Collectors
Our 321 Stainless Steel merge collectors are handmade using USA bends. Engineered to obtain the high flow and velocity only available in a true merge collector, these units are available in 2-1, 3-1, 4-1, 5-1, 6-1, and 8-1 configurations for any application. Every unit is purge tig welded and incorporates a transition spike that is internally blended, making the transition from the primary tube to the collector as smooth as possible. This smooth transition maintains exhaust velocity, improving volumetric efficiency.
