Stainless Headers Mfg. 4 into 1 merge collectors are manufactured from American made 304 stainless and fabricated right here in their U.S. facility. Purge tig welded and hand built to exacting standards, these merge collectors offer a hand blended internal chamber with a collector spike for optimal exhaust scavenging. This collector is configured with a 1 ¾” inlet, made to go over a 1 ¾” primary tube. It has a 2 ½” minor merge diameter and transitions up to 3 1/2” as its final size. Collector overall length is of 14 1/4 inches. These collectors work great for side exit header applications because of the domestic material. They trim nicely after the fender pierce point has been determined.
