The Stainless Works 4-way collector is a mandrel-formed exhaust component built from 304 stainless steel for corrosion resistance. It channels four 2-1/4" ID primaries into a smooth-flow tapered 4" OD single outlet to maximize flow capacity. CNC-formed with a smooth taper for consistent transitions, these collectors include a lifetime warranty and are proudly made in the USA.
