The Stainless Works 4-way formed collector is constructed from 304 stainless steel with a smooth-flow taper, accepting four 1-5/8-inch ID primaries and merging to a 2-1/2-inch OD single outlet. It offers maximum corrosion resistance, includes a lifetime warranty and is made in the USA, making it suitable for compact header configurations where four primaries need to be combined into a single moderately sized collector.
