The Stainless Works 2" four-way merge collector is a TIG-welded reverse-cone collector with slip-fit 2" primaries and a 3-1/2" OD single outlet. Made from 304 stainless steel for corrosion resistance and durability, the collector is designed to guide exhaust flow cleanly into the outlet. All TIG welding and a slip-fit design simplify assembly, and the product is backed by a limited lifetime warranty.
