The Stainless Works 4-way formed collector is made from 304 stainless steel with a smooth-flow taper, configured for four 1-7/8-inch ID primaries and a 3-1/2-inch OD single outlet. With a lifetime warranty and built in the USA, it supplies a higher-capacity merge for header systems demanding a larger collector exit to optimize flow into oversized downstream exhaust components.
