The Stainless Works 4-way collector is a mandrel-formed exhaust collector built from 304 stainless steel for maximum corrosion resistance. It merges four 2" ID primaries into a smooth-flow tapered 3" OD single outlet to promote efficient scavenging and reduced turbulence. CNC-formed with a smooth taper, these collectors include a lifetime warranty and are proudly made in the USA.
