The Stainless Works 4-way collector is a mandrel-formed header component constructed from 304 stainless steel for corrosion resistance. It merges four 2-1/8" ID primaries into a smooth-flow tapered 3-1/2" OD single outlet to optimize gas flow. CNC-formed with a smooth taper for consistent performance, these collectors include a lifetime warranty and are made in the USA.
