Stainless Headers Mfg, Inc. - 4 into 1 Mild Steel Merge Collectors

Our 4-1 Mild 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 base exit, straight exit, or transitional exit 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.
