The Stainless Works 4-way formed collector is manufactured from 304 stainless steel with a smooth-flow taper, accepting four 1-7/8-inch ID primaries and merging to a 2-1/2-inch OD single outlet. It’s built for corrosion resistance, includes a lifetime warranty and is made in the USA, offering a reliable merge point for headers that need slightly larger primaries feeding a moderate collector size.
