The Stainless Works 4-way collector is a mandrel-formed exhaust collector constructed from 304 stainless steel for corrosion resistance. It integrates four 2-3/8" ID primaries into a smooth-flow tapered 3" OD single outlet to encourage efficient gas evacuation. CNC-formed with a smooth taper for predictable flow, these collectors carry a lifetime warranty and are made in the USA.
