Our straightexit merge collectors are ideal for the fabricator who wants to either leavethe header as an open header design or finish it off with a flange. We supplythe collector with a straight section of tubing that is welded on right at thecollector merge. Available in a variety of primary inlet and merge sizes, these merge collectorsare handmade using American made bends.Engineered to obtain the high flow andvelocity only available in a true merge collector, every unit is purge tigwelded and incorporates a transition spike that is internally blended. Thisinternal blending and spike design makes the transition from the primary tubeto the collector, as smooth as possible. This smooth transition maintainsexhaust velocity, improving volumetric efficiency.
